Ok pal. Your video is amazing but it miss the final touch.
Here's what to do for the 2nd video.
Put the camera on a stand
Make the table and you in front of the camera
Bring a car batt. And a non slipping surface so when you put those items on the table we can see the wires clearly long and straight going from device to another.
Add a writing diagram to you video in the end of it so techs can copy it for their use.
Eventually
Thank for the video.
Yours. Bighouse
DIY: Car Modz, Thanks for the quick tutorial specifically about the "Relay harness" topic. I realise that some folks here dont understand that you were not giving a full tutorial on HID kit installation. Since most videos concentrate on HID full kit installation they dont do much explaining about the function of the relay harness. Thanks for that
Thanks for making the video bro! I had issues with HID OEM plug in setup. This helped me get a relay harness with the direct battery. First try everything lit up. Only way HID should be hooked up. Don't learn the hard way. These harnesses go for like 20 bucks.
Great video thanks for explaining this concept! Awesome makes alot more sense!
great video ,,the best video that I've seen on here...you answered two of my questions...
Thanks for the Info....sorted out my issues .... :-)
I have a problem with honda dio 2014 i thing i net a relay .. i bay one ..but te problem no have any idea wow to conectet
I wanna install hids on some fog lights but my truck did not come equipped whit any ,so I need to run the wiring ,what's a good way to do this I need some help .
Would a 2001 Buick Regal require a harness? I've had them on my car before, but they last around a year give or take before acting up.
How do you disconnect the two pin black connector from the wire harness to the bulb?it is crazy tight and doesn’t come off
Hi,i have an hid kit with relay and when i turn on the lights the relay is continously buzzing.¿What do you think it´s the problem?
The ballast are DLT F7 (70 watts)which are really 55watts.Without the relay they work ok.¿The continous noise is a problem?
Where is a safe place can I mount the extra rounded wire harness? please answer quick
hello sir, i have just bought HID kit H11 for foglamp and i want to install it to my car suzuki, the HID ballast is written 45 watt, should I use the relay for installation ?
What if you are adding fog lights to a car that doesnt have them where would i connect the socket which activates the harness
What brand HID Ballast are you using?
Do I need relay for 2014 Nissan Versa Note?
I want to wire my Hids on a separate switch, so, could I take the signal wire from the relay, cut off the connector, and soder on a switch? if this wouldn't work, how would I go about putting them on separate switch. Thanks
What type of harness is that i need that one. Thanks
Is this recommended for a basic 35w 6000k kit for a 13-14 Accord?
Where do you put the silver box in your engine bay lol I’m so confused
where did you get your relay harness???
what brand wiring harness is this?
Hola buen dia, donde puedo conseguir este kit para una xentec de 55 w. Debo instalarlo pues tengo una jeep compass 2013 y estas se apagan y vuelven a prender periodicamente. ..... Gracias por tu atención.
What is stock wire?
I retrofit my lights on my 2007 Suzuki swift. Stock plugs are h4 and the projectors I retrofit are H1 bulbs. I bought a h4 relay harness(it uses one h4 plug from driver side and it connects to the battery too),two ballasts and two H1 xenon bulbs. I put everything together and it works fine,except one thing. When I switch on my lights and close them after a while, trying to open them again only drivers headlight came on. If I try on/off several times the passenger side work too. I thought my ballasts are bad and I bought new ones. But still the same. Is that a problem with my relay harness?
That usually is either a bad relay or a bad hid ballast. What brand are you using?
Why not plug in the second signsl wire?
How can you check if you have a faulty ballast or a faulty relay harness? My right headlight went out so I tried switching the bulbs and the bulb from the right side was now lit up on the left side and the bulb from the left side wasn't lighting up on the right side. I'm assuming since both bulbs worked on the left side that narrowed the problem down to the relay harness or the ballast.
+Chris Agra Yup. It can be the relay harness or the connection is loose on the driver side. Unless you have the hi/low hid kit unplug the relay harness and plug it directly to the stock headlight socket and check if that works. If not, you have to swap ballast left to right.. but make sure the connections are solid. Many times.. it is the connection came loose.. either on the ballast or the stock wire harness or the relay.
Nah ha da down best video explanation FACT
Thanks for all the "DIY sweet mods!" Totally makes a world of a difference!!
8 months ago, like you I did the HID mod using DDMs kit and TRSs Fog kit. I happen to read that you were going to upgrade to TRS HID kit. Did you upgrade yet? If yes, did you end up using the relay harness? Is it really necessary? I just bought the HID TRS kit for my 2013 Honda Accord coupe V6 and will be installing soon. I understand why the relay is used and its benefits. I just don't want to have to rewire or find room for the relay if I don't really NEED it. It was bad enough finding room for the ballasts.
My current setup... I have the 35W TRS XB H11 hid bulb and f3 35w ballast for my low and the XB Type S for my fogs. I have not installed the relay harness and had zero issues for the past 2 years.
How do I bypass the ballasts as they seem to be problematic in most cases?
You can't bypass the ballast. Dont purchase ebay hid kit.
If I use relay harness, the bulbs are connected will be turn on all day whenever the engine is on?
Not at all. The only thing the wire harness does is draw that power straight from the battery only when you turn on the headlights. You connect the power and ground to the battery but there is also a signal switch you attach to one of the stock headlight socket. So when you turn on your headlights.. it activates the relay that makes the connection to the battery.
if i want to put hid for my drl, will this relay fix drl error???
You need to install a capacitor if you want to use HID as DRL. www.vleds.com/in-line-cap.html
I have a 1998 buick lesabre custom, After I installed this relay harness for my 55w hight beam it left me with
one plug connector from my headlight unplugged. there was nothing else to plug in. Is this normal?
Walter Topij Yes that is normal it only uses one original plug the other can be left unused.
shouldn't the unused one be plugged up somehow? what can i use to plug it up?
@Felix Salinas You need to purchase a set of capacitor to add to your hid setup to fix the flashing problem.
Do I need relay harness for 2014 Honda Accord
Jose Viera If your using 35W ballast, there really is no need. If your using 55W ballast, I would consider using a relay harness. I'm using 35W ballast with no relay... Not a single problem for almost 3 years.
+DIY: Car Modz I am using 35w ballast I check all the wires connections and still have little flickering, can't be possible because of the cheap ballast kit that I'm using
Jose Viera If your having flicking issues.. then wire harness "might" solve the problem. What kind of HID kit are you using?
how do you tell if its going bad my passenger headlight stopped working it try's to come on but shuts off I got my fog lights to turn on by switching out the resistor I think that maybe my problem hopefully
arnoni11 What car do you have and which HID kit did you purchase.
DDM tuning and a 2009 jeep liberty its a 55w 6k I think its my resistor I ordered another relay hopefully that's it
I have an 09 f150 the light on the battery side turns on and the other light gives me a one second flash and turns off. I have brand new hylux hid kit do I need the relay.??
JAL1LUX For your vehicle module, you will have to use a relay harness kit. If you connect the HID ballast directly to the stock wire harness the ignitial current draw will trigger the smart junction box to disable the circuit ( example.. your lights turning off after a sec.)
DIY: Car Modz Befor the hylux HIDs I had some cheap ebay ones and those worked fine, they didn't need the relay. So I installed the 1 hylux on the side it worked and the other the chap ebay one so I could have 2 good lighs and it still didn't turn on. Was that cause of that hylux was sucking up all the power.?? Thanks
Great tutorial! I need your suggestions, I went to DDM tuning to buy HID kit for my 2014 accord sedan V6. This guy at the store asked me to use relay harness and so I bought it. I do understand that relay harness takes the power directly from the battery. What might happen if I do not use the relay harness? And what might happen if I use relay harness?
James Lee Everything will work with or without the relay harness for the Accord. Some vehicles need the relay harness to work but for Hondas, you don't need it so I don't use it. Well at least for 35W kits you don't need it.
DIY: Car Modz Thanks. I got the 35W. I went ahead and canceled the relay harness and tried connecting the HID bulbs using the ballasts, but the lights don't work. I flipped the connections like you suggested still dont see them coming up. Think the bulbs dont work?
James Lee take a look at the video: ruclips.net/video/AVT0pDEgDscT/видео.htmlhere are 2 connectors that you might have to flip. One would be on the HID ballast and the other one to check is the plug that plugs into the original wire harness. If the lights does not work... I would turn on the headights and try flipping the plug that goes into the stock headlight harness first.. if that does not work.. flip the other connector.
DIY: Car Modz Got them running now. Connection had to be tighetened. But I hear the buzzing sound in the passenger side. That should be fine or something needs to be readjusted?
DIY: Car Modz Appreciate the quick help bro
Do I need a relay harness kit for 2000 silverado
+CHALO Torrez Yes, you will need a relay harness for your car.
Do I need a relay harness I have a 2015 camaro and I'm not sure
+JsBlazIN ruclips.net/video/OxwCxxfOXh0/видео.html
Do you recommend HID or LED? And where do you recommend buying from? Thanks
+Jason Rozycki HID will be brighter compared to LED. Take a look at www.theretrofitsource.com/ . I'm currently using 35W F3 ballast with H11B 35W TRS HID bulb.
@@DIYCarModz As you said about there r negative and postive connection to the ballast and the stock wires, won't it short if we try an error to know which one is which like you did?
I have a 2012 Honda Odyssey and only one side turns off. It comes back on when I turn off and on again. Would I need a relay? And also only one side needs to be plugged into to factory socket? Does it hurt if I plug both side in?
vpxdough Using a relay "might" fix the problem your having. It could be a bad hid ballast or ignitor. Before you go spend your money on a hid relay kit. I would swap the HID bulb and then check and see if the side that does not turn on switches. If not, then I would swap the HID ballast from left to right and check again.
It happens on both sides but more on the right side.
vpxdough Can you link me the HID kit your purchased?
Wish I could, but it was a gift from someone.
I'm confused as to if I need a relay or not. I have a 2013 Honda Accord LX.
If you want to use it.. buy it. It will work with or without it. I have a wire harness for my fogs on my honda fit. For the accord I do not. It's been 3 years and no problem.
What if my stock sockit it doesn't fit to the harness socket...its different
You have to purchase the correct relay kit. For example, my car uses H11 for the low beam so I have to purchase a H11 HID relay kit. It will come with an adapter that will fit a H11 socket.
@@DIYCarModz yes it seems I got the universal ones so I just use the adapter that comes with that makes the socket just become positive and negative and I hooked up the positive to the positive of the headlight and then I grounded it with the negative. The thing is that the kit that they have on the video it's actually the one that I have but I guess their lights fits with that one so they forgot to mention the part about the socket :-) thanks for your help I really appreciate it
the only thing is instead of the negative terminal , you connect the end to a ground, probably a metal bolt directly attached to the frame. Otherwise well done post.
Bharath Kumar You are correct. Both will work. If the negative post on the battery is grounded to the frame as well. Thank you for watching.
whats the relay for
Relays are used to get direct power from the batt to the ballast or anything else that needs power when you need to turn something on and off. And using a relay, the wires used are usually of thicker size gauge to allow more current to flow. If you just connect it directly to the cars factory wires, sometimes these wires are too thin and you run the risk of over heating them, ruining the wire.
So let me get this straight, Signal will only be coming from one side to power the ballasts?
When you flip your headlight on... the signal wire will trigger the relay on the wire harness to pull the power straight from the battery and from there it will power both of the ballast. You do connect both of the ballast to the wire harness.. not the signal wire. The signal wire is plugged into the wire harness. .not the ballast. You do not need to connect both the signal wire plug.. it just needs one of the stock bulbs plugged in.
I was just curious because only one signal socket is used.
Shane Rhabb Correct.. only one side has to be connected..... If you want.. i suppose you can connect the other side.. I see no harm in it.
The harness I have only has one signal connector but the one in the video has 2. So in mine both sides would run off of only one signal. Whatever works.
Shane Rhabb Okay in that case.. yes just use one. You just need one.. The harness you received will work just fine.
WHat's a stock wiring harness?
+tase25 And where is it?
Stock wiring harness is where the stock halogen bulbs are plugged into. It's the wire that you'd normally connect to the bulb before inserting the bulb back into the headlight fixture.
There are 2 stock harnesses, but you only need to use one. Based on my above explanation, it should be obvious now that the stock harnesses are located behind the driver and passenger headlights.
giving us a tutorial from your office cubicle eh?
could u explain in better terms on relay hardness you buy it already made or make it. one relay per light or just one. I know how to but others are confused.explain in details don't assume people understand. bad explaining
Relay kits are not necessary.
Too much wires…
Your camera work was so bad i couldn't stand watching the whole thing.
