I have recently bought a 72 F250 Camper Special with a 360. Neither of the fuel tanks are registering. The previous owner tried to install a different switch and cut all the wires. I have the correct switch and need to find out the correct way to wire it up. any help would be great. Thanks

I don't have the wiring diagram, but likely a DPST(double pole, single throw) switch is used.
I also don't know what the switch looks like physically, but electrically speaking:
The "common" post of the switch goes to the dash(guage), the other two posts accept the wires from each tank sending unit. Thus the two positions of the switch gives you readings from alternate tanks.
