Do they not match up? I keep seeing the colors you listed as being the same for the 7 pin.

On mine, I could see a solid yellow,brown, and white wire, which would seem to indicate that they are the same. Doesn't hurt to check with a multimeter before hitching up, though. For ground, I'd just attach it to the frame (make sure to clean the area).

Yeah, I bought the adapter, the hell with hacking up my wiring, which later on down the road can corrode and cause issues, I know I am of no help, but just giving you what can occur.
