Help a non-electrician out here!
I am about the furthest you can get from an electrician, but I have done minor projects. I just changed out the wiring harness for a new stereo in the TT. I am installing a wireless back up camera...

I agree totally with SoundGuy. Do not rely on color codes. Get a DVM. Harbor Freight has them pretty cheap. My new MH had the color codes on the rear connector all wrong. Many MHs manufacturers extend their chasis. The RV manufacturer apparently re-wires with whatever color they have at the time. BTW instead of hooking power to the parking lights I would connect to the positive voltage that feeds to the Trailer connector if possible. If it is a V10 that power would be on anytime your ignition is turned on.
