aftermarket fuel gauge 1997 Chevrolet C2500 5.7L
My fuel gauge and oil pressure gauge are dead and I need to wire aftermarket gauges. The fuel gauge has me stumped already. It requires a hot wire, a switched wire which I have no problem setting up. The "data" wire from the tank seems to be a closely guarded secret. I have a bundle of wires running along with my fuel and brake lines to the back of the truck. Which wire is going to be the "data" wire? Probably not referred to as a data wire but I am a master mason, not a master mechanic. I work on all 5 of my vehicles and am mechanically inclined. I just need to know which wire goes to my new gauge.
