2002 Newmar Mountain Aire 3778 Wiring Diagram

Help! I am looking for a wiring diagram for my coach. I need to trace the 12V line/wire from the coach side to its power source. I do not have 12 volts where it connects to the step controller. Newmar has been no help and does not offer tech support to owners only to technicians. I have followed so many inks to dead end wiring diagrams. Thanks Y'all.

I assume you have Kwikee steps. Do you know the model? There is a trouble shooting guide floating around.
I'm betting that the ground needs to be REALLY cleaned and then top coated with di-electric grease once re-attached and tightened down
