Unfortunately I do not have the any wiring diagrams for the Monaco. So cannot help in that category. I have in the last 6 months, replaced my inverter, battery disconnect solenoid, rear AC and thermostat, coach batteries, dash stereo, and am currently in progress of replacing furnace. I did have to rebuild the entry way for the Monaco as well.
You may find some one in the "Power Train Forum" on this site that can give you some direction.
Good Luck.
