Re: Dual tank rocker switch
Sorry about that! It's a 78. The switch is a 5 pin, 2 top, 2 middle and one bottom left.

Re: Dual tank rocker switch
Left side (with three wires) is the sender wire selector. The middle wire goes to the gauge.
The other side (two wires): one is hot when ignition is on, the other connects to the fuel valve solenoid to pull the valve to the other tank. With the switch in the off position (empy bottom right contact), the valve springs back to the default tank.

Re: Dual tank rocker switch
You mean power TO the solenoid, right?
