Replacing heater and countertop, found this tucked behind lower reinforcement along floor. Brown, brown-white stripe, and black. Has been broken a
LONG time. Only has 8 volts on it when ignition on. When I put a toner in it moves forward through lower harness and behind the drivers side panel. As
I type, thinking might be gas tank sender, but not enough wires. Ideas? or something under the missing seat?

I just have the 77-78 electrical diagram with me. It shows tan / double white-tan is main/aux fuel sensors and black is the fuel tank selector
solenoid.

It is the same on the 75 with breaker points diagram and the 75 with HEI diagram and the wires go thru a 10 wire connector to the side body harness
and then thru a 2 wire connector on the LH frame rail.

Thanks for the replies. It was the fuel selector and tank sensor wires. I use waterproof connectors, the right size and color wires, a heat gun to
shrink the connections, and for the first time in what I am sure is many years, fuel gauge readings. Plus found new fuel lines under there, Just hope
they replaced them ALL.
Also installed Bovee Onan pointless system, reasonably easy, but a little time consuming as I get my bearings. I now know why the power drawer 6k is
called a BEAST. It is one.
ran poor, pulled the plugs and nice color on the front, while rich on the rear. Once I popped the plugs back in and pushed the coil wires on, purred
like I think it should. I bet the coil wires could, should, be replaced. too many years sitting. dielectric grease is my newest best friend for darn
near every electrical connection in this coach.

Thanks again,

Jack
