In the Newell book that came with the coach, there is a Termination list (1-24) of all the wires and there function for the rear electrical panel in the engine bay.  The wire color for each terminal matches the book exactly. I can not find any information or electrical schematics for the electrical components ( Relays, Breakers, Solenoids). I have the Fan Control relay pulled out and I'm going to test it now. Does anyone have any electrical schematics for this wiring panel?

Update:

The fan control relay functions correctly on the bench. Looking at the bottom of the relay you will see the relay terminal connection.  Terminal #1 (+12 volts) and terminal #4 (-12  volts) energize the internal coil of the relay.  Terminal #1 is jumpered to terminal #5. The power for the hydraulic fan solenoid is connected to terminal #3. Terminal #3 and Terminal #5 are a set of normally open contacts that close when the relay is energized.  The orange wire that connects to Terminal #1 gets it's power (12 volts) from terminal #4 on the terminal block mounted in the panel. According to the book, terminal #4 [[is the DDEC Ignition - #12 Orange.]] this is not correct!! Terminal #4 is actually Ignition Fuel valve - #12 Orange, and Voltage regulator - #12 Brown!  I have checked this and indeed I have 12 volts on the orange wire going to the fan relay terminal #1 when the key is on.  I DO NOT have a ground (yellow wire) on terminal #4.  I will now try and locate the other end of this wire.  I could just put a ground wire on terminal #4 and I believe everything would work fine.  I just want to try to understand where this yellow wire goes. I added a picture of the bottom of the relay to show the connection points.
