HVAC blower wiring schematic

My 1995 Ford motorhome blower does not work. The motor works fine. All threads say to follow the circuits to troubleshoot. That is nearly impossible with wiring harnesses. I need a Ford F- Series HVAC wiring schematic to find ALL of the electrical components, in order to test. Please help.

Blower motor relay

My 35' Pace Arrow is built on a 95 F53 460 Chassis. It does not appear to be the Evans HVAC system. I have purchased three separate ford wiring diagrams. The all show completely different color codes. My system 12v main power to the hvac system is Blue wire w/ red stripe. It goes directly to the Blower relay pin #87. The blower motor has one blue wire and one blue w/white stripe. All of the wiring diagrams show brown/orange and orange/black wires. I am gettin very frustrated.

Pin 85 and 86 on my 2000 7.3 Excursion have power all the time with key off energizing the blower relay running the batteries down. With the key on I can turn the blower off. Apparently the switch panel is getting power with the key off as the flow of power has to go through the switch. Switch off key off a few seconds later the blower starts up. I have the blower unplugged each time I park the truck. Any suggestions/help? Where is the blower high relay located I have no manuals and havent' been able to find it.
