7 Pin Chevy Trailer Wireing Diagrame. I hope this helps some folks, because it's pretty tough finding this online. Look at the wiring diagram for your truck and determine the designation given to the ground location for the taillights.
Not sure which wires attach to what on your trailer connectors? WOW, interesting - seems like a pretty obvious screw-up, I think we have a couple test-trucks parked out back. Search for threads on Pollak socket here on the forum, plenty of threads with pictures.
Don't try yellow to yellow and Note that the pin assignments are consistent with yours, but not the wire colors.
That diagram is very clear on that.
A wiring diagram is a simplified standard pictorial depiction of an electric circuit. I was wondering if anyone has a dodge-specific wiring diagram that deals with things like: a purple wire, no yellow, an orange stripe, a red, no white - all departures from the standard wiring. Refer to your trailer service manual and plug installation instructions to avoid wiring problems that may damage your trailer, brake controller or vehicle!
