7 way plug wiring color/diagram
The 7way plug on my 2017 35'? Grand design travel trailer had some wear and gave "trailer disconnected" signals on dash. I purchased a GM recommended male plug (Pollak). The old connector is molded together so I am unable to see how colored wires connected to male 7-way plug. I even hack sawed old plug and still not able to see the colored wire connections. The Pollack plug has wire color suggestions on it. The colors seem to hold out, match with yellow left over to go to center (auxiliary). Does anyone know the proper color wires to 7 way male plug?

Travel trailer 7-way plug wiring diagram-Bing search comes up with plenty of options, and if I were a gambler, I’d put money on none of them being applicable to GD. Why not try calling customer service with your year, model, VIN, and build date. Can’t see why they wouldn’t help you.

These are standard pig tails that should just wire right to the color of the wire and to the pin in the connector. This is a standard wiring diagram. @traveldawg has posted a good diagram above.

I got a Mictuning 7 Pin Plug & Junction Box to make a test break out box.
It's wire colors matched my 5er pin box junction box wire colors and the wires were on the correct pins in the plug.
The truck's 7 pin wiring lands on the correct 7 pin terminals, Ram just uses different colors for their wires.

Thanks for all the suggestions and great diagrams. I have also placed an e-mail to Grand Design customer service and am waiting for a reply. I believe that I am on the right track in rewiring the new plug. Again, thanks.

Strange, but nothing in my owners manual. I got a reply from customer service with wiring diagram.

There is no reason to not trust the trailer wiring diagrams you find on line. 7-Ways are universal be it utility, livestock, boat, or RV trailer. They show the wire color/pin location view looking at the end of the plug, so you have to work really hard to screw it up.
