Wiring Diagram for 1990 Ford Chassis Free

Due to health, we have not been able to travel much in the last few years. Decided to get the old motorhome in shape to go one more time and found so many needed parts hard to find. Looked forever on the internet for a shifter cable and wound up finding a new one almost in our backyard. If anyone needs that source let me know.

I have the chassis wiring diagram for the 1990 Ford Chassis that I will share with anyone who needs it. We paid a mobile repairman $250 to rewire our batteries after replacing them without marking the wires so would just like to save anyone else some money.

Hello,
Wiring diagrahm? I would love just to know where the fuel pump relay
is located? I mean which one????

Can you help?

Thanks
