Certified Mobile RV Technician, Darren Koepp, teaches you how to remember which pin is which when you are troubleshooting a faulty 7-Way RV plug.
Note that there is a 'Traditional' color-code spec and an 'RV' color-code spec. Darren will be explaining the 'RV' color-code spec NOT the 'Traditional' color-code spec.
Here is a great article on etrailer that does a great job presenting the different specs between the 6-pin and the different 7-way standards: www.etrailer.c...

Thank You, Thank you, Thank you! Out of all the videos I looked at no one explained it better than you. This saved me. The wiring diagram that came with the plug is totally useless. It might be easy if you hand the old plug still connected but mine ripped off...so just the bare wires. The only difference is I didn’t have a ground (white wire) still worked great without it. Thanks.
here is a cool tip for you and everyone else watching. If you take a 10 amp blade fuse (not sure the best amp fuse to use but you will know) you can stick it in the black (12v) and Green (trailer lights) or whatever color is for your trailer running lights openings and it will light them up. I do this at night as its just cool to have all the running lights on at night and sets your RV out from everyone elses. Before you go in for the night you can just pull the fuse out to turn it off. They actually make a device for this purpose that plugs into the end of the 7 way with a switch but its like $30 or so. The fuse is much cheaper of course. If you use the correct size fuse then its safe and protected from getting stupid as the fuse will just blow ands shut off the lights. Boom! my RV tip! lol.
He's going off what the plug says I go off what I know black is hot to charge and red is reverse tho
At 5:15, you called the center terminal (yellow) your "auxiliary". I believe the center (yellow) is your backup lights. The black terminal (constant 12 volt, that charges RV battery), is sometimes called auxillary.
Left is YELLOW ? THIS IS CONFUSING AS HELL.
I just needed to know which one to disconnect so I am not trying to charge eight 12 volt lithium batteries off of my truck when I am traveling down the road! Thanks for sharing...👍
Green and brown and mixed up I think. Both trailers I’ve wired up this week, green was right turn
When I plug in my trailer my breaks lock up. Do I switch the black and blue wire pin positions?
I have been a auto mechanic most of my life, 21 years in a Ford Dealership (Senior Master Certified) It is strange how these wire colors are totally different from normal trailer wiring. I knew there was a difference between like Commercial vs agriculture type codes but this is CRAZY. Normally with any trailer wiring YELLOW = Left Turn/Brake Lt GREEN= Right Turn/Brake Lt and BROWN=Tail/Marker lamps White is Ground and that is all unless you have electric trailer brakes which is BLUE And of course you Aux 12v+ but as a general rule you only need 3 wires for a trailer yellow, green , brown if you are grounded good through the ball (Redneck Way)
I’ve been watching videos all day and I agree 1000%
I would hope that he would either take this video down or say this is his way
and not the standard way.
You should never ground through the hitch ball, that is not an electrical conductor. As a matter of fact, when working on trailer electrical the only thing connected should be the electrical umbilical and nothing else.
@@RVingwithG This video is the correct wiring for 7-way RV umbilical.
Where did you get your wire colors from? I started in the 70s with GM pickup trucks helping to repair trailer wiring issues on my family's dairy farm. We always just used same color as the trucks and I still do today. Only thing trailer brakes are sometimes red or blue depending on trailer. And 12 volt hot is usually red or black. But everything I have dealt with is green (usually dark) for right turn, yellow left turn, brown tail marker, and ground white. So I was just curious.
Iam not sure why but when you look this up it claims his color codes are "standard". I always wired green for right, yellow to the left, brown for tail. Better remembered as green for the grass to the right, yellow for the line to the left, brown for the shit behind you. This is the standard for heavy duty air brake trailers but of course to make shit complicated they need to switch it u. A different industry.. Then blue for brake, and red or black for 12 volt hot. Which ever is left for your center pin or reverse lights.
Thank you for helping me understand!
I was lost.
Hi Bob,
Glad it helped!!!
Cheers,
Darren
Thank you. I tried many ways to make mine work and watched a bunch of videos. After watching yours fixed the plug right away.
What if I don’t have a blue wire
Very nice, thanks. How and where would you recommend tapping into this to install white reverse lights on the back of my travel trailer? Maybe my 7 pin has no reverse wire?? Can you recommend a good RUclips video that shows this install being done?? Thanks much
To solve this riddle, I would start with the tow vehicle side of the connection. If you look at the socket, the center pin should be where the back-up lights are wired to. Not all OEM’s agree with this though and some do not even wire it but leave it to you to determine what that ‘Aux’ pin will be used for. In that case you may find a wire coming out of the back of the socket that is available for connecting to ‘something’.
So, start with trying to determine if your tow vehicle has that center pin energized when the back-up lights are on. If not than you will need to add that wire from the back-up circuit on your tow vehicle to that center pin - tow vehicle side.
Once that tow vehicle step is completed and confirmed, try to solve the riddle by connecting to your trailer. If still no back-up lights when the center pin is energized than you will have to wire your trailer back-up lights into that center pin on the plug.
Hope all that makes sense. That center pin of the 7-way really is the best (and only available) pin to control that back-up circuit as the other 6 pins have pre-defined jobs to do.
Cheers,
Darren Koepp

My Ford F250 is not detecting my trailer when I plug it into the truck. We think the problem is in the truck receptacle. What wire detects the trailer.
Thanks

Hello I been watching your videos great job very informative thank you. I'm working on a new light bar for better visibility and wondering if there is a easy way to hook light to light alarm so I don't forget them on . I have a sea Breese national any help would be appreciated.
Thanks my man!!! Sheesh, spent hours testing, trying different color codes online…..on the 4th try I used your color code and now my camper lights are correct!!!!! Beware of all the wiring diagrams on google!!!! AJK
Whoah... Wolverine is working on trailers now?
The problem is too many different ways companies color wire these systems and as usual and causes confusion making the hook-ups more difficult and time consuming and cause a search a figure out session. on my trailer #3 is Brown wire, Tail/ Running lights- #5 yellow wire, L Turn/Stop lights- #1 White wire, Ground- #2 Blue wire, Trailer Brakes- #7 Back-up lights, Center- #6 Green, R/turn/Stop lights and #4 Red wire, AUX 12V & Charging, for me this is really crazy where is the standard Code? I won't even bother to explain the other Diagram I have! Really it's it's a big ball of confusion!
Thanks. I just subscribed to your channel because you make great videos.
Thank you for watching. I have many more on the way.
Thanks Darren , this is most helpful way to clear head about wires and trailer connectors . However i'm worry about fact that sometime you feel like da RV .. and you admit that -HONEST MAN !
Myself i'm bit less honest when comes to times that i would let anybody know about switching identities even for second . i know how to keep secret and i won't tell nobody that yesterday i was a refrigerator and day before i was a John Deer Tractor .
thank you
What does Auxiliary do? Thank you for this video, My Chevy Colorado plugs upside down. Re a that don’t know have blown my 30A trailer fuse trying to push it in. I guess the Aux would be the wire to put a switch on to keep the truck from drawing from trailer battery when the battery Voltage goes on low mode (12.1)? I would like to install that or I guess a Dc to Dc charger would resolve that!
very helpful. MY QUESTION IS ...i share a 16' dual axle trailer with a friend . we both have chevys with a factory 7 pin outlet. he doesn't have a brake box in his truck because he hauls very light loads. i want to haul heavier loads. i DO have an E brake box installed in my truck. if i wire our trailer up with a 7 pin wire set up can we BOTH use it or will he have a problem because he DOES NOT have an E brake box in his truck? thanks a lot.
😀
HI Darren,hope you are doing fine,
I have my trailer tail lights that just wont light, although my turn signals, my break lights, my emergency light, my electric break all work perfectly. I had an issue with the connecting cable from the car to the trailer lately. It got tangled up with the hitch and caused a short somehow. Two fuses were busted in the truck fuse box. I replaced them. So I dont know were to look. I replaced the 7 pins cable. Do you have an idea for what I should look for?
Thank you in advance an thank you for sharing your expertise, much appreciated.
Best regards,
Sellig
Key on top clearance lights 12volts hot all the time Black blue red left turn brown right turn trailer brake what ?
I have one trailer tire that locks up when I go in reverse and not stepping on the truck brake. I had to remove the blue connector in the junction box to get rid of power to the brake. Now it doesn't lock up. Why is this happening? How do I fix it? Thanks, and THUMBS UP!!!
Very smart and useful approach. Thank you for posting.
That's great explanation for American vehicles for the color code but I do not believe Toyota and other foreign vehicles follow the color code that American trucks/cars have???
Yes I'm wiring a new progressive dynamics power converter /charger. I'm also rewiring my 7 pin cable on camper side and on my campers wiring diagram it calls for black hot from 7 pin trailer plug to be wired into the refrigerator and lights to camper or to the converter itself. Where would I wire in my black hot into my converter at to my black battery positive lug in my converter?
Nice! A very simple explanation needed to replace rv plug we drug several (100+) miles!
Center should be BU Back Up - to lock out Surge Hydraulics when your in reverse.
Great idea, thanks. Where would you recommend finding the paint pens.
Oh my goodness THANK YOU! It worked
*FACING FORWARD:*
*9/3 = 10 & 2 on the steering wheel (L/R!)*
*11 O'Clock Clearance Lights (Back To the Future as in **11:59** AT 11FT!)*
*1 O'Clock (Past 12=12V) lol or think of the band "112"!*
*5 O'Clock (Need Them Brakes for 5 OClock Rush Hour!) Easy one!*
*7 O'Clock (Don't be 7 Feet under-GROUND!!!!) LMAO*
and
*Center = Yellow (Yellow Center Line) straight to Auxillary (cuts right thru both lanes think CLU from TRON!! )*
I've seen other videos that use the same "remember" method, but the color of wires are different. Same functions though.
Obviously you know nothing and will start a nice fire for folks...yellow is ALWAYS LEFT TURN,GREEN IS ALWAYS RIGHT TURN,WHITE IS ALWAYS GRIUND,BROWN IS ALWAYS MARKER LIGHTS,
Well, to be fair, that's why there are folks like me to fix it when folks like you wire RV trailers using the 'Traditional' standard when it is supposed to be wired to the 'RV standard'. I cannot tell you how common it is to come across this issue in the RV repair side of the house. Please understand that there are two color code standards, if not more, for these types of wiring connections. The circuits are all the same on the plugs but the color of the wire changes based on 'Traditional' versus 'RV' color standard. There's also standard for Agricultural and then another standard for semi trailers. You can follow this link for a image of the two standards I'm referencing:
www.etrailer.com/question-136117.html
That sure is easier to remember than just a diagram.. I don't move my trailer as I live in it, but now I have something I can share with others. A thumbs up as usual, and I'm already subscribed.
Hi Terry, Thanks for the comment and it is good to have you here! More video's coming out soon!
Would be more interesting if you had stopped shaking toe connector around as you speak. Other than that it was a good tutorial.
Very helpful with color coordination!
Hernandez Patricia Moore Steven Jackson Mary
How in the hell did you come up with that?
Every body on the internet doing this wires different from the other so don’t feel bad I called them out too
Thanks for all the correct ways to do repairs
Easiest to understand by far. Thanks.
Hope it helps. Thanks for watching. Happy camping.
thanks but i have a orange wire in the center? and the white and black where wire}ed the same where just the ground is i put on a new plug but i dont have the 12 volts
I don't have a blue wire on my Kaufman
What other color could it be?
What is the brand and model of you tester? That sure would be helpful.
Does this apply to all rv's? I have a 2008 StarCraft trailer
You are the man
Can you help me find the same tester? I like that there is an impression in the plastic to help remind me what the illuminated light is referencing - Robb from Virginia
Hi Robb,
I picked up the one I am using at a local auto parts store when we lived in Texas. I just now did a search on Amazon for 7-way tester and found several to choose from - some even fancier than mine for under $10.
I have also made a really fancy test box that I use in my diagnosis and troubleshooting but that is for another topic/video at a later date when I make some video's on my tools.
Thanks for watching and Happy Camping!
Cheers,
Darren Koepp
wow when you show me this. went out p it out wire went bad all was keroid
Thank you. Blessings to you.
The paint pens are a great idea for reference. great video. hope your super busy in PA. I'm in Sequim working on rvs and I'm slammed I'll send em your way if i don't have time to do it all! And boy it's been a hot few days!
Is this the same for a 16 foot trailer just like a covered utility trailer, we had the seven pin come out of the bumper and the guys at work drug it for 30 feet so we had to change the truck and the trailer now am I guys why did wrong and I need to fix it
What about reverse lights?
What about reverse lights?
Why are the trailers wired differently than the plug? Every trailer I have seen uses brown for marker lights, yellow for left turn , and green for right.
The circuits land on the same pins but the color codes change depending on if it's RV standard or utility trailer standard. There's also a standard for agricultural and even big semi trucks have their own standard. Wnows why this is, but if you're not aware of it you could be wired wrong if you use the wrong standard.
I agree with wiring. I wish that RVIA made manufacturers follow a code for every unit. I've been in units that are backwards, different color wires all together, it's just ridiculous. (Not exclusively with 7 way?
Thanks love it god bless
your right for standard rv ty cargo little different all my trailers are wired in rv style ty
Thanks for watching
I just bought a 2005 Rockwood pop-up trailer. I have a 2016 Nissan rogue. The harness on the Nissan is four prong and the 7 pigtail on the trailer don’t match. So what do you suggest I do to plug these two together?
thank you. i was wondering why my used pop-up trailer was not NOT braking during a gain test. "They" snipped my light blue.
Awesome...thanks so much.... I like simple ways to remember things. Good on ya Bud!
Very nice, another electrical code to remember is Copper to Copper = short, Copper to iron = ground, Copper to air = open.....
I believe this is called Auto-Industry Standard and RV Standard. There are 2 ways to wire a trailer and if you look at what pins on the plug do what job the trailer plug does the same job regardless of which Standard it is wired to. I prefer the Auto Standard as the 4 wires from a 4 pin trailer plug do the same job from 4 pin to 7 pin.
that's how I wired my plug on my cargo trailer the same colors you used. Everything works but what's puzzling is on my Chevy Silverado the colors definitely do not line up with the plug on my trailer. There's a light green wire right in the center where I have yellow on the plug. There's no white wire on the truck side it's a thick black wire instead. But everything works like it's suppose too. What I was wonder is if I could wire a back up camera using the trailer wires? If light green is reverse and the thick black is ground then it should work? Has anyone tried it this way rather than take the truck light assembly off to wire it up through reverse lights?
Thanks Darren! Going to go see if my pigtail is following the rules.
I am wondering why RV plug wires do not correspond with the other industry trailer wiring guidelines? Example, green and yellow for turn signals and brake, brown for running lights.
Great video
yellow left turn green right turn Brown parking lights White ground blue electric brakes purple reverse light black or red 12v power! This is the right way of the wiring code this guy has been wiring things wrong
need congress pass law so all trailer s the same. The width of RR tracks and truck kingpins are the same by law.
I agree with your color code
That man don't need to be making videos teaching people wrong
lee tijerina some are different
lee tijerina you’re right. I was a tractor trailer mechanic and they use seven pin connectors.
White ground
Black tail lights
Brown marker lights
Yellow left turn
Red stop lights
Green right turn
Blue auxiliary
This was code from east coast to west coast, from the Arctic down to Argentina. You can see where the RV industry has adapted most of this. Brown and black were usually tied together
@@t.s.tractorworkstrickland5828 What part of the video was incorrect? As a Certified RV tech I present repairs on RV's and the video I presented was for RVers and the colors I presented followed the 'RV' spec.
Have a look at this article on etrailer and click on the box for 7-Way wiring. www.etrailer.com/question-136117.html
Look closely at the wire colors in the center 'RV' spec and compare it to the 'Traditional' wire color spec to the left. I don't make the rules but as an RV repair professional I have to know the differences between the two specs and correct all the incorrect wiring that was done by those that are not aware that there are different specs for RV's... Again I don't make the rules but I do know there are differences between SAE and RV.
I will be cutting a follow-up video where I will focus on the different 7-Way specs to help enlighten those that did not know that RV's were wired using different color codes.
Cheers,
Darren Koepp
Thanks
excellent work thanks
Is the auxiliary pin 12v hot? What would that be used for?
My question is lets say the wire color is not the same. I test each wire on TV looking for lt,rt,marker,hot,trailer etc. Whatever the function for that individual wire it still goes to the same position on trailer plug correct?
Hello. Is there a way to make a 7 pin act like a 5 pin as far as lighting? I'd like to have dedicated brake lights and other as just turn signals. Thanks
which one is reverse?
My four pin set up dragged on a recent trip and all the pins got removed by the road. I want to convert to the 7-pin outlet on my truck. How do I do this?
H0W DID YOU MAKE 2 SEC TIMER THAT YOU PLUG INTO SYSTEM
Our sister company T3 interface,inc is building those now and should have them on our My RV Works store soon. Keep watching this link for announcement when they are available: myrvworksstore.square.site/shop/tools/3
I have a crazy question.. should the 12v run straight to the battery ?
Thanks a lot.
Question...it doesn’t matter if the pigtail goes in sideways regarding the wiring pattern correct?
Thank You Sir, helped me out
yes , thank u
Awkward ive Never seen a pigtail with this color code. But the position has always been the same
Your video was the best one I found well done . Gave you a like and I subscribed thanks..
Thanks, I used your video today with success!
yellow left green right brown running red 12v white ground centre reverse
There are several standards for the 7-way connections. In this video I cover the RV standard not the SAE standard. The circuits land on the same pins but the color of the wire changes. Read the description of the video. There's a link to Etrailer where they offer clear pictures. I cannot tell you how many times I've had to make this repair on RVs that come into the shop because they were not wired to the correct RV standard - they were wired to the way you are referencing and that is not correct for an RV. So if you're going to be working on this stuff it might be good to familiarize yourself with the different standards so your work doesn't end up in the shop too LOL...
Appreciate it man I watched 2 other videos and no luck but your way you explained it was easy and simple
Does the center pin auxiliary have 12 volts constantly?
That all depends on how the tow vehicle was wired. Typically it is supposed to be the backup circuit - but it is called AUX. I have seen it wired to a switch in the cab to turn on docking lights. One of the test plugs that I used in the video will help sort it out.
Cheers,
Darren
I use it for reverse
Awesome explanation of what each wire pin does
do the left and right turn pins also work the brake lights? Is the brown pin for a trailer brake?
This helped out tremendously. Thank you!
Well Done and very useful video. Thanks
I've been to 2 different places trying to find an adapter to plug in to my flat 4 way on my truck so I can plug into my 7 way blade on my camper. Walmart, auto zone, no luck!! Where do I find one? I can find the female end "which is what's on the camper" but not the male end that I need to go on my truck. I hope I explained that right. Where can I purchase it??
That's not something you're going to find. The purpose of the 7-way on the trailer is one of those circuits is for a brake. So on your truck you would need to have a brake controller. It's tied into the brake pedal and you can adjust the gain excetera. So you're 4-way flat wire on your truck is just for lighting. Because your trailer has a brake circuit you're going to need additional pins on your truck side. I hope this makes sense.
Great video, easy to follow and very clear!
This video was a huge help thank you so much for the upload
Why do i have power at my trailer brake pin when no brake is applied?
Your very welcome
Thank you! Simple explanation!!!
