Dual Tanks

Does anyone have the wiring diagram of the dual fuel tanks, for both the gauge switch and the tank selector. I would like to have this working once I get my truck working.

1970 F250 390.

1967/72 F100/350 Styleside factory dual fuel tanks: In-cab tank and optional 25 gallon auxiliary tank, mounted on the inside of the left frame rail in front of the left rear wheel.

The fuel tank selector valve is manually controlled.

The selector switch mounted under the dash to the left of the column only changes the fuel gauge from the auxiliary tank to the in-cab tank or vice versa.
