Easy Way To Remember Wiring Of A 7-Way 'RV' Plug (RV Standard) 

Hi Terry, Thanks for the comment and it is good to have you here! More video's coming out soon!

You got lucky. On 99.9% of all trailers; the yellow is the left turn and break and green is the right turn and break and brown is the running lights. Blue is trailer Breaks Red is +12volts Black is Reverse …

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.

Hope it helps. Thanks for watching. Happy camping.

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

Thank you for watching. I have many more on the way.

Hi Bob, Glad it helped!!! Cheers, Darren

Darren is starting up a new company where he will be making tools for techs. One of the tools he has designed is what he is calling the RV Light-show. The user will connect the 7-way to this test box and select the wiring standard (Cargo trailer or RV). That will change the colors of the LED's when the individual circuit is energized from the text box. He is also making a version of that tool that will pair to a smart phone so you can walk around and energize the different chassis circuits while you are working on them. At last count he told us he was up to 30 different tools he will be developing. Very exciting times. Keep an eye on his new website as he works with our web developers and tool makers and starts adding tools: www.t3interface.com Happy Camping My RV Works Media Team

My RV Works, Inc. The current production tool that does that is a box called the Mutt. Its designed for exactly that purpose. If he can beat the cost of them that would be awesome, cause they’re still a bit steep.

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.

Thanks for watching

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

Thank you! and you are welcome!!!!

I have 06 Chevy with fifth wheel and trailer short,ha? Maybe it wasn't rats

First step would be to get one of those text plugs to determine if the issue is the truck or the trailer. Look for a continuity to ground fault. If on the trailer sometimes it is easier to just pull a new wire instead of investing time locating the fault.
