Spartan Chassis electric trailer brake wire?

I spent hours trying to find the four wires that Monaco runs from the front of the motorhome to the back. Unfortunately the four places that these wires go to are not the same four wires between each place. I never did find the wires at the hitch area of the motorhome.
I ended up mounting the brake controller in the engine compartment where I can reach it to adjust the sensitivity of the trailer braking. Good luck in finding your wires.
