I have to replace my 7 way socket due to corrosion and disconnected wires. After removing the old socket I was expecting six wires colored wires, however, I have only 5 wires, a Red, Green and 3 white wires. I can't find these wires called out in any electrical diagram that I have. I've gotten the white wires narrowed dow to turn signals and running lights. Any idea what the red and green go to? 09 Nimbus
I just rewired my '99 so maybe I can help. My lights have separate turn signals and brake/running lights so I added an adapter. The white wires should have a number on them that would correspond to a schematic from FOT. On my coach the larger green wire is a ground. The small red should be the running lights. There is a larger red wire that supplies 12volts through the plug. I used one of these to see which wires were hot when each of the lights were on and verified with a voltmeter which one was my ground.

Thanks Much for this. Interesting my bigger wire is red and the 3 whites and green are the same gauge.
Here are the standard 7 way color codes for both RV and toad/trailer: 7 Way Diagram - AJ's Truck & Trailer Center (https://www.ajtnt.com/Info/7-Way-Diagram) Your plug with 5 wires does not have the 12V aux and trailer brakes I'm guessing.
