Needing Wiring Code For The Trailer Pin Box

[jcalkins]

I recently had to replace the 7 pin cable from my 5th wheel pin box to the truck. Even though I took the "before" pictures, I must have missed something and now my signals don't work and I'm not sure if there are other issues I might have caused. When I opened the junction box under the pin box there are a bunch of color coded wires. One lead is from the rv, one from what I assume is the brakes and one from the 7 pin cable.
Does anyone know where I can get a schematic that shows these leads and what colored wires go to what?

I think your looking for this:

Your break away will have one lead attached to the battery lead and the other to the trailer brake circuit ( usually blue).
