Could any of you guys help me out? I'm looking to find a wiring diagram or just some advise would be great, I have an old dual tank pickup, 75' gmc 3/4 ton. The guy I bought it from took the aux tank out along with all the wiring and the actuator. I just ran a line to the remaining tank, but I would like to have a fuel gauge for that one tank. I know where the harness would of plugged in, and have looked in all my local scrap yards and can't find a harness for my pickup. I have the supplies to make my own harness, but besides one wire coming from the sending unit to the plug on the firewall I have no clue what else to do. It has the round plug similar to the tail light plug with 4 prongs in it. Can anyone help with what I need to do??
