I have recently bought a 83 4x4 truck with dual tank. The Guy I bought it from has put a toggle switch on for the tank selector in the truck cab. The toggle has broke now, which has caused my gas Gauge to run to past full when its on.I just wanna run the driver side tank,cause the passenger tank leaks. I see five wire on the toggle. Is there anyway to get my fuel gauge to do the driver side tank without spending tons of money on a toggle and also what color wire runs what?
