This video has given me more information and explanation than 6 hours on google and other youtube videos. I bought a set of relays from Amazon that did not state they were 5 pins so I've been trying to see if there's any way to avoid a return and use them as an SPST. Thank you for the video, it has helped tremendously.
I actually studied electronics technology in VoTech and Trade School, but was out of the industry for the past 20 years, this was a great refresher course for me. It all came back to me, thanks for posting. 👍👍
of course there are other uses for the 5 pin but this is a beginner video.. i will UPLOAD a video on other uses for the 5 pin when i get back in the garage.. THANKS for watching..
One thing I would like to see on your video is to advise viewers to mount this relays with the mounting tab on top. Most imported relays are not water tight and can short out of fail with ease if mounted in any other direction. Great video and excellent explanation. 👍
I have been around the automotive repair world for quite some time and I have attended numerous training events. This is by far and hands down the simplest, most understandable and direct explanation of the relay that I have ever heard! Thank you for posting!!!!
I’ve watched about 100 videos on relays. After watching both this one and the fist one you did on the 4 pin where you turn on the a/c i do not need to watch another. Thanks!
When I want a short sleeve shirt, I buy TWO short sleeve shirts. I put the first one on and tear it off like Hulkamania Running Wild. Then I put the second one on. Good vid!! Very well done. Stay gold.
This was what I have been looking for. I've watched so many youtube videos and they all recommended 5 pin and all I am doing is lights...so I bought 5 pin and have had the toughest time trying to figure out what the darn thing does and why my switches are powered upside down...this video was perfect. The one question I do have that may be answered in the comments, but didn't see it right off the bat, was what do I do with the extra wire now? Do I leave it? do I cut it? Do I cap it? Appreciate your guidance. Thanks again for a great video!!
Great video man, seriously. The drawings make is all click for us visual learners. I don't need or want over the top graphics or background music, just the facts. Thank you, thank you for helping me learn something.
Good video. I usually use 5 pins even though I know I don’t need to. I honestly barely can find a decent 4 pin from a reputable brand. It never hurts to have the 5th pin so I just use them 99% of the time. Actually just did a project using the rare 87A. I have a daytime running light on my truck that is powered by an ignition circuit. Interrupted it with a 5 pin relay triggered by the parking brake ground. Parking brake to 85, ign to 86, ign to 87A, 30 to DRL. pull brake, DRL shuts off when the relay switches to 87. Works like a champ.
Love love your wiring vids!!! Thanks man ! I have some fans I need to wire I just came across the 4 pin relay definitely seems a lot easier .. Looking forward to your upcoming vids!
Exactly to the point lots of youtube videos have the 5 pin bought a 4 for a horn setup but other videos made me lose my nerve and you reassured me that I had it right :)
Such a great vid... I was listening to a new mixed tape and didn't want to listen but watched your vid accompanied by Mary. Jammed out and learned the wiring set ups with cool-ease. your diagrams... Best Regards!
Holly crapper! You made the relay go from a shell game to idiot proof in my minds-eye! Thanks so much for demystifying the relay and how to hook it up.
Hi Chris - I learned a lot about relays from your videos. I have a 5 pin starter relay on my 2005 Volvo v50. It won't start and I want to try to a repair I'd seen on a forum where the mechanic grounded the relay to the strut tower of the car. I just want to confirm that to try this repair of grounding the relay I would ground from the #85 pin of the relay to the grounding point (nut on strut tower). Thanks, Tom
Im glad i subbed to your channel. Mate its hard trying to explain this to a family member who is blind as a bat! Lol 😂. If he wasn't 2.5 hrs away i would have wired up his spotlights in an hour! Cheers from Australia 👍
i have a video on wiring up KC long range lights.. with a relay... they use the halogen H4 bulb and you can see 100 feet away perfect.. wiring a relay in real life.. for some reason it has little views..
@@chriscraft77022 thanks heaps. 😊 now I can send it to him! Poor bloke has been trying to get his spotlights going since Friday! From the beginning? And end I'll told him check all the earth connections? 3 relays and 4 toggle switches later and replaced some wiring? So many issues I'm saying Australia is very humid and living on acreage with a ton of dust I would constantly have to clean terminals. Thanks for the link! Cheers 🙂 👍👍👍
I think availability is a reason why people may use a 5 pin. In my circumstance right now, I need a 4 pin normally on relay, but I don't feel like ordering and waiting for the part. Since I can pick up a 5 pin relay anywhere and wire it as such, win.
Thank you now i know what's required, its autumn here so time to re attach the long sleeves ready for cooler weather along with the legs to my pants...
Love your video man very well explained thanks a lot for doing this a lot of people doesn't understand how to do I really appreciate that my friend I have to watch that a couple of times before I understand
I watch both ur videos for my son mustang fans his high speed wouldn't work and videos and knowledge help alot keep up the videos bro and show tht chevelle when u done!!!!
Chris, great relay video. Could you make a video that explains how to wire two switches to a single accessory using relays. Also three switches to a single accessory using relays. Keep up the great work.
You can use a 5 pin relay to over ride a thermostatically controlled fan with a toggle switch as well. I'm sure there are other similar uses, just can't think of any at the moment, but definitely not in place of a 4 pin.
Hi Chris, Great video with helpful explanations. Your videos on relays are the only ones that englightened me. I'm less than a novice on relays as I have never worked with them and only became aware of their exsitence few days ago, but I would like to learn how to use them on cars. In both this video and your other one titled "the automotive RELAY explained...", did you assume two power sources for the two circuits: one for the 85 - 86 circuit and another for the 30 - 87? It seems that you used two power sources in the other video on air conditioner, but I am not sure on this one. As far as I understand, personal cars only have one power source. In this case, would you need same gauged wires for both circuits?
A 5 pin relay (SPDT) is required if you need an open circuit while the relay is being powered. When power is off the relay will switch to N/C. This would be used if you want something to turn on when the power to relay is off.
A 5-pin relay can be used as a 4-pin relay. If the price difference is not much, I'll buy a 5-pin relay so I have the option of using it as either 4- or 5-pin. Thanks for the useful video/explanation.
I'm by no means an expert but from the research I've done, a 5 pin relay is essential for applications you need to power 2 different accessories like high/low beams. A 5 pin can constantly power low beams until the solenoid (electromagnetic coil) has current from switching on your high beams which magnetically pulls the iron switch to the second circuit which turns off the other. Relays 4 or 5 pin types allow many car parts to operate without drawing high Amps because the electromagnetic coil doesn't require high current while things like pumps, electric fans require high current to properly operate. So those parts don't burn out, instead the relay does and it protects the expensive components. Only $10 for a relay, $100 for a fan. It's also important to have a fuse between the high power + line (battery/JB) and the relay and all components after.
Hi Chris, I have a 4 wire after market gauge from Glow Shift and my gauges go off when I run any accessory. So I wanted to hook up a relay but I’m confused. The gauge has a 12v to battery, 12v from a switch, ground and another wire for when you turn on your lights it dims the gauge. Can I use a 4 pin for this? I’m not sure where I hook up the 12v switch for the relay and for the gauge itself
I'm trying to power a two speed stock ford fan watching this I believe I can just use a five pin relay. I enjoy this style of seeing this drawn out being an artist it works with my brain.
hi Chris great videos I just have a question for you as i hooked up a five pole relay the way you said to but am wondering if I just leave 87a not hooked to anything? I installed a bumper that had 4 led lights in it . hooked 86 to my head lights 87 to my led's ran a 12gauge wire from 30pin straight to the battery with a 10amp fuse then ran pin 85 and led ground to chasey ground . but the lights come on right away without anything turned on. when I do turn ignition on and put high beams on the led lights shut off and work correctly the way I thought they should but they stay on when i turn ignition off. i just left 87a not hooked to anything. thanks for your time Chris hope to hear back from you soon .cheers mark...
Nice clear explanation there. How would I go about wiring a relay to power a car stereo with a main starter battery and a leisure battery. I want to use the leisure battery when the ignition is off. Thanks
This is pretty old but I'm gonna ask anyways. I'm wiring this to a starter solenoid on an atv so it will start off of a toggle. I assume what you have wired to as the fan would be the power to the positive on the solenoid?
Chris, quick question if i may, I'm working on rewiring some foglights on car i have and I'm following some directions from the internet,i understand everything however i noticed that they are running battery to 87 instead of 30, why and will that hurt anything? its a 4 pin relay,this project im working on has been posted on the internet for years for the kind of car im working on and countless people have done, it,im just one of those that likes the "traditional way" to do things and when i saw that it made me wonder, thats why i ask.
Hi Chris, I’m doing relays for my headlights on my 69 charger, I’ve been researching a lot and thought I could go with 2, 4 pin relays for low and high instead of 5 pin like some of the videos I’ve seen because non of them used the 87a pin. But in your video you use a 4 pin and 5 pin, why is that, and is that what I should do and how would that get wired? I’m running separate power wires to each relay with a separate fuse for each relay. I will splice into the high beam wire for one relay and low beam wire for the other relay. I do want to do separate circuits in case the low or highs went out for some reason, old car wiring/connectors if you know what I mean. Lol
that’s how all modern cars wire them.. one 4 pin and one 5 pin.. you don’t need to wire them separate.. I would have a video on this out but I’m not working on the old car right now.. I have the new lights and everything ready. you need to really think your project through before you do stupid things.. you can use your existing power wires going to old lights to turn on the relays.. wire them separate but not necessary in any way
@@chriscraft77022 thank you I’m asking questions because I want to do it right plus to remove the load on the switch and dimmer. Will your way be using the 5 pin on the low beam and using it to turn on the 4 pin for high beam, or will the 5 pin be used second and control both the low and high beam, or some other configuration, if there is another. So instead of using battery power direct from the battery on pin 30, I can use the low beam wire to power the relay if so would that go to 30 and 86 or power direct from the switch to 30?
@@The01Bookie no... mount the 2 relays by the headlights.. low beam power wire goes to 86 on the 4 pin.. 87 from the 4 pin goes to 30 on the 5 pin... so the high beam power wire goes to 86 on the 5 pin.. there are many many diagrams on this because all cars are wired like that from the factory..
@@chriscraft77022 I'm trying to get my head around this, but I would basically treat the "low beam" as my thermo switch power to fan and "high beam" as manual power on to fan?
Hi Chris I needed a 12V 5 pin Relay for the PT Cruiser to power the indicators but unfortunately the 12volt 100 Amp Relay didn't work for the PT Cruiser as the indicators stayed on & the lights didn't Flash & so I'm going to use this waterproof 12Volt 100 Amp Relay unit for a radiator electric cooling fan that has 2500CFM & 90 Watt & I can buy this radiitor electric cooling fan for NZ $80.28 which not a bad price & I asked the Seller on AliExpess if that 14" inch electric fan can also with straight flat fan blades & apparently these come with straight flat blades as well which is great & the radiator electric cooling fan unit they show in the picture has curved blades & the difference between the straight flat bladed fan units is they force more air through the radiator than the curved bladed fan units but the curved bladed fan units are slightly quieter running fan units but I prefer more air flow through the radiator having straight flat bladed electric fan units & that's the difference between curved bladed fan units & the straight flat bladed fan units Kind Regards Peter
Perhaps a dumb question but can a 4 prong relay be used as a 3 prong relay? I have a 3 prong relay on my horns in my car. So If I plug battery to 30 and the wire to the horn button is a ground (so 85), that should basically work also no?
Really appreciate the explanation. I have a pop up headlights could you do an explanation of how best to wire them up. I’m not sure if a 4 pin or 5 pin would work best
Could this relay be used for a backup camera to provide two sources of power? Basically to switch between power from the reverse bulb wiring for backing up to then providing constant power from the battery? Constant power used to keep the camera on.
Thanks for the video!!! I have a couple questions, may be stupid questions but nonetheless idk... 1. Using the diagram at 4:18 of this video, if the qtip is at 87a and you DO NOT have anything wired at 87a, will your battery die? My guess would be no. 2. Is there a certain amperage that needs to go to 86? If I were to use a "fuse tap" on an existing accessory that turns on, only when the car is on (like an accessory that gets power from ignition) would that be enough? 3. If it says 30, that goes from battery straight to the relay , is that the max amperage this relay can withstand? Thank you in advance. I installed a universal power window kit on my friends 88 chevy truck. Pulling bout 500hp. I only used a rocker switch. He got so much shit hooked up as is with gauges etc. But he killed his battery by forgetting to turn off the switch. I'm looking for another way. Without taping into the ignition wire.
Very Good job of explaining using a diagram. What I was looking for is the reason that some relays with 5 pin are stated they are for a 1976 Corvette blower motor when the original was a 4 pin. I received a 5 pin but don't have a high speed on my 1976 Corvette I have been restoring, but the original one was just 4 pin. The single one on the 4 pin is for ground but the 5 pin I received dose not identify ground on the two pins if any. Just wondering if that its the reason of having no high speed blower on it and knowing which pin that ground was suppose to go on if at all. The resister is new and all the other speeds work but high with this 5 pin relay.
I am using a relay to install a rearview camera. Do I run the wire from 86 to my accessory wire when I turn on my key. I think I can but just wanted to make sure. Thank you Levi J DeVerney.
yes.. but you don’t need a relay for a camera. why can’t you just run that “on with key” wire to power the camera..? I have a back up camera video, btw
usually you would run thicker wire to compensate for the voltage drop... is the camera like a high quality HD or something? because if it is just a normal cheap back up camera you do not need a relay for that.. unless you camera is pulling 10 amps for some strange reason
I want to create a car alarm like in your previous video. How do I use either of these (4pin or 5pin) to have the parking lights on disarming the horn when starting my car...?
Thanks for the video. It is very helpful. I do have a question, and wording it may be difficult, so here it is: If the 5 pin is wired like a 4 pin and the switch (pin 86) is off (resulting 87a to pass the current), is it correct to say that power will NOT be drawn from the battery (pin 30) if 87a is open/not connected to anything?
Chris Craft wanted to see if you can help. I have Polaris Ranger with cab heater that has quit working. I used a test light to determine the relay needed to be replaced. I put on new relay checked positive with test light and it works but when I check the wire (87) going to the heater control panel there isn’t any power. Any ideas? Thanks in advance fo any help.
Hi Thanks for the great explanation. Can you please explain the way a 1966 Lincoln Continental rear window 5 pin relay works. It is super confusing and I want to know if I can replace with a modern 5 pin relay. Thanks again.
Great video....... I still need help. I want to wire an Air Horn that I want to work a several ways. I know how to wire with a relay to allow the Air horn to work off my stock Horn button. I would also at times like to break that connection so it does not work off the stock horn I would also like to have a separate switch that works all the time not dependent on being connected to my stock horn. What is the best way to do this...... Thank You
Very impressed video and nicely explained.Thanks.I am trying to connect a second passenger electric window switch on the drivers side as there isnt one .In my case ,can I use the 5 pin relay to use 87 and 87a for up /down?
Would this be ideal when hardwiring a dash cam to continue recording while parked and away from vehicle. I'm new to this but you've explained it the best.
@@chriscraft77022 I do have one 12v out, so I'll be using that single outlet for dash cam, a gps speedometer, my interior floor lights etc etc. So I'm trying to hard wire as much as I can to free up my outlet. Too many wires hanging around drives me crazy. So should I hardwire all these accessories?
The cost difference between the 4-pin and 5-pin relays are quite minimal, particularly particularly if you are purchasing a 6-pack or more. If you have both relay types incorporated in your vehicle, camper or boat, there is an advantage to using the 5-pin relays, since all relay applications use the same relay. I keep one spare 5-pin relay in my vehicle glove box to replace any failed 4 or 5 pin relay in an emergency.
Thank you for this. I’m about to wire up a drag race only car but need headlights when exiting the track. The car has no wiring in it. I’m starting from scratch.
Why would a 5 pin relay be used on rear wiper? I wouldn't imagine it needs power all the time. It does have a delay when it's on, perhaps that would explain why? Thanks for any thoughts
Hello Chris - have you got letter referencing for Hella relays? I have a P and an S on my headlight washer relay which I know is not working but would like to remove the cover and test. and have the facility to do it in the future. I have the European DIN chart numbers from 1 to 88 and the wiring colour codes for European DIN standard. There is a 72 page pdf file on Hella relays by Hella but not letters P or S. Thanks.

I'm by no means an expert but from the research I've done, a 5 pin relay is essential for applications you need to power 2 different accessories like high/low beams.
A 5 pin can constantly power low beams until the solenoid (electromagnetic coil) has current from switching on your high beams which magnetically pulls the iron switch to the second circuit which turns off the other.

@@chriscraft77022 The 2 batteries are on a split charge relay. So the alternator charges both.
is it ok to put the switch at the negative? making it a negative switch?
This is pretty old but I'm gonna ask anyways. I'm wiring this to a starter solenoid on an atv so it will start off of a toggle. I assume what you have wired to as the fan would be the power to the positive on the solenoid?
yes
Chris, quick question if i may, I'm working on rewiring some foglights on car i have and I'm following some directions from the internet,i understand everything however i noticed that they are running battery to 87 instead of 30, why and will that hurt anything? its a 4 pin relay,this project im working on has been posted on the internet for years for the kind of car im working on and countless people have done, it,im just one of those that likes the "traditional way" to do things and when i saw that it made me wonder, thats why i ask.
it wont hurt but in USA we run power to 30.. just leave it.. it works either way
@@chriscraft77022 Thank you very much,appreciate your input.
Hi Chris, I’m doing relays for my headlights on my 69 charger, I’ve been researching a lot and thought I could go with 2, 4 pin relays for low and high instead of 5 pin like some of the videos I’ve seen because non of them used the 87a pin. But in your video you use a 4 pin and 5 pin, why is that, and is that what I should do and how would that get wired? I’m running separate power wires to each relay with a separate fuse for each relay. I will splice into the high beam wire for one relay and low beam wire for the other relay. I do want to do separate circuits in case the low or highs went out for some reason, old car wiring/connectors if you know what I mean. Lol
that’s how all modern cars wire them.. one 4 pin and one 5 pin.. you don’t need to wire them separate.. I would have a video on this out but I’m not working on the old car right now.. I have the new lights and everything ready. you need to really think your project through before you do stupid things.. you can use your existing power wires going to old lights to turn on the relays.. wire them separate but not necessary in any way
@@chriscraft77022 thank you I’m asking questions because I want to do it right plus to remove the load on the switch and dimmer. Will your way be using the 5 pin on the low beam and using it to turn on the 4 pin for high beam, or will the 5 pin be used second and control both the low and high beam, or some other configuration, if there is another. So instead of using battery power direct from the battery on pin 30, I can use the low beam wire to power the relay if so would that go to 30 and 86 or power direct from the switch to 30?
@@The01Bookie no... mount the 2 relays by the headlights.. low beam power wire goes to 86 on the 4 pin.. 87 from the 4 pin goes to 30 on the 5 pin... so the high beam power wire goes to 86 on the 5 pin.. there are many many diagrams on this because all cars are wired like that from the factory..
@@chriscraft77022 ok thanks for your time and help.
Glad I found your video/tutorial, very clear and well presented 👍
If I wanted to normally power a fan with a thermo switch, but then be able to manually power the fan on with a switch, would I need a 5 pin relay?
yes ...
@@chriscraft77022 I'm trying to get my head around this, but I would basically treat the "low beam" as my thermo switch power to fan and "high beam" as manual power on to fan?
yes exactly
@@chriscraft77022 Is this preferable to say using a 4 pin and adding a bypass circuit to the thermo switch, using the addition toggle as an interrupt?
There are several thermo switches to use ... and many ways to wire it up,., check out my bmw thermo switch video if you don’t know
Dude loved your video, made understanding relay simple
Do you have a video explaining how to read a wires volt and amp
Hi, great video! Question, the on/off switch going to pin 86 has two pin connections, one for 12 volts and the other is used for what? Thanks
it is ran in series ..
Love the Blue Seas Fuse block. Blue Seas is a high quality company.
Did the video for using a 4pin & 5pin together for Hi/Lo beam lights happen?
Ive been trying to figure out relays for a boched command start install on a 98 Dodge Ram ..nightmare. Thanks helped alot!
Hi Chris I needed a 12V 5 pin Relay for the PT Cruiser to power the indicators but unfortunately the 12volt 100 Amp Relay didn't work for the PT Cruiser as the indicators stayed on & the lights didn't Flash & so I'm going to use this waterproof 12Volt 100 Amp Relay unit for a radiator electric cooling fan that has 2500CFM & 90 Watt & I can buy this radiitor electric cooling fan for NZ $80.28 which not a bad price & I asked the Seller on AliExpess if that 14" inch electric fan can also with straight flat fan blades & apparently these come with straight flat blades as well which is great & the radiator electric cooling fan unit they show in the picture has curved blades & the difference between the straight flat bladed fan units is they force more air through the radiator than the curved bladed fan units but the curved bladed fan units are slightly quieter running fan units but I prefer more air flow through the radiator having straight flat bladed electric fan units & that's the difference between curved bladed fan units & the straight flat bladed fan units Kind Regards Peter
Perhaps a dumb question but can a 4 prong relay be used as a 3 prong relay? I have a 3 prong relay on my horns in my car. So If I plug battery to 30 and the wire to the horn button is a ground (so 85), that should basically work also no?
Really appreciate the explanation. I have a pop up headlights could you do an explanation of how best to wire them up. I’m not sure if a 4 pin or 5 pin would work best
Could this relay be used for a backup camera to provide two sources of power? Basically to switch between power from the reverse bulb wiring for backing up to then providing constant power from the battery? Constant power used to keep the camera on.
So can I use a 4 pin to connect the coil wire from a lawn tractor to go to ground to kill the engine or do I need a 5 pin? Thank You
Thanks for the video!!! I have a couple questions, may be stupid questions but nonetheless idk...
1. Using the diagram at 4:18 of this video, if the qtip is at 87a and you DO NOT have anything wired at 87a, will your battery die? My guess would be no.
2. Is there a certain amperage that needs to go to 86? If I were to use a "fuse tap" on an existing accessory that turns on, only when the car is on (like an accessory that gets power from ignition) would that be enough?
3. If it says 30, that goes from battery straight to the relay , is that the max amperage this relay can withstand?
Thank you in advance. I installed a universal power window kit on my friends 88 chevy truck. Pulling bout 500hp. I only used a rocker switch. He got so much shit hooked up as is with gauges etc. But he killed his battery by forgetting to turn off the switch. I'm looking for another way. Without taping into the ignition wire.
Why didn't you use a momentary contact switch?
Very Good job of explaining using a diagram. What I was looking for is the reason that some relays with 5 pin are stated they are for a 1976 Corvette blower motor when the original was a 4 pin. I received a 5 pin but don't have a high speed on my 1976 Corvette I have been restoring, but the original one was just 4 pin. The single one on the 4 pin is for ground but the 5 pin I received dose not identify ground on the two pins if any. Just wondering if that its the reason of having no high speed blower on it and knowing which pin that ground was suppose to go on if at all. The resister is new and all the other speeds work but high with this 5 pin relay.
I am using a relay to install a rearview camera. Do I run the wire from 86 to my accessory wire when I turn on my key. I think I can but just wanted to make sure. Thank you Levi J DeVerney.
yes.. but you don’t need a relay for a camera. why can’t you just run that “on with key” wire to power the camera..? I have a back up camera video, btw
@@chriscraft77022 hi chris I tried installing the camera but there is not enough voltage going to it. I have a 2008 Suzuki forenza.
usually you would run thicker wire to compensate for the voltage drop... is the camera like a high quality HD or something? because if it is just a normal cheap back up camera you do not need a relay for that.. unless you camera is pulling 10 amps for some strange reason
Thanks man, that literally was so easy to understand! Keep em coming!
I want to create a car alarm like in your previous video. How do I use either of these (4pin or 5pin) to have the parking lights on disarming the horn when starting my car...?
Excellent presentation, communicative description
Thanks for the video. It is very helpful. I do have a question, and wording it may be difficult, so here it is:
If the 5 pin is wired like a 4 pin and the switch (pin 86) is off (resulting 87a to pass the current), is it correct to say that power will NOT be drawn from the battery (pin 30) if 87a is open/not connected to anything?
it will NOT draw power
@@chriscraft77022 Got it. Thank you for clarifying!
Chris Craft wanted to see if you can help. I have Polaris Ranger with cab heater that has quit working. I used a test light to determine the relay needed to be replaced. I put on new relay checked positive with test light and it works but when I check the wire (87) going to the heater control panel there isn’t any power. Any ideas? Thanks in advance fo any help.
Hi
Thanks for the great explanation. Can you please explain the way a 1966 Lincoln Continental rear window 5 pin relay works. It is super confusing and I want to know if I can replace with a modern 5 pin relay.
Thanks again.
Great video....... I still need help. I want to wire an Air Horn that I want to work a several ways.
I know how to wire with a relay to allow the Air horn to work off my stock Horn button.
I would also at times like to break that connection so it does not work off the stock horn
I would also like to have a separate switch that works all the time not dependent on being connected to my stock horn.
What is the best way to do this...... Thank You
Very impressed video and nicely explained.Thanks.I am trying to connect a second passenger electric window switch on the drivers side as there isnt one .In my case ,can I use the 5 pin relay to use 87 and 87a for up /down?
Can the on off toggle be used on relay trigger ground 85 ?
yes
Would this be ideal when hardwiring a dash cam to continue recording while parked and away from vehicle. I'm new to this but you've explained it the best.
cant you just get constant power from the cigarette lighter? that’s what I would do
@@chriscraft77022 I do have one 12v out, so I'll be using that single outlet for dash cam, a gps speedometer, my interior floor lights etc etc. So I'm trying to hard wire as much as I can to free up my outlet. Too many wires hanging around drives me crazy. So should I hardwire all these accessories?
Thanks man, got yourself a new subscriber.
Sorry if this is stupid question but where are we getting that 12v that goes to pin 86??
The cost difference between the 4-pin and 5-pin relays are quite minimal, particularly particularly if you are purchasing a 6-pack or more. If you have both relay types incorporated in your vehicle, camper or boat, there is an advantage to using the 5-pin relays, since all relay applications use the same relay. I keep one spare 5-pin relay in my vehicle glove box to replace any failed 4 or 5 pin relay in an emergency.
now the 4 pin are more expensive.. 😳
Thank you for this. I’m about to wire up a drag race only car but need headlights when exiting the track. The car has no wiring in it. I’m starting from scratch.
Why would a 5 pin relay be used on rear wiper? I wouldn't imagine it needs power all the time. It does have a delay when it's on, perhaps that would explain why? Thanks for any thoughts
Nice explanation ! IN your example of 5 pin, won't the low beam headlights be on the whole time ?
no, it switches them off (87a) when energized
What dictates the required amperage of the relay, does this relate to the item you will run e.g. 25 amp fan requires at least a 30 amp relay?
yes.... just get 40 amp to be safe.... thats all I buy now
Hello Chris - have you got letter referencing for Hella relays? I have a P and an S on my headlight washer relay which I know is not working but would like to remove the cover and test. and have the facility to do it in the future. I have the European DIN chart numbers from 1 to 88 and the wiring colour codes for European DIN standard. There is a 72 page pdf file on Hella relays by Hella but not letters P or S. Thanks.
Which would I use in order to wire up a group of LEDs to be running lights then also that same group of LEDs to be signals?
5 pin
This was extremely helpful, thank you bro!
