Well after swapping a 465/205/14/60 combo into my blazer, I cannot get my gas gauge to work. The rest of the truck is working nearly flawlessly but I cannot figure this gas gauge out. Before I swapped the pedals for the 465 into the truck, I disconnected several wires and harnesses from the steering column. There are two wires coming from the back of the instrument cluster near the gauge that I can't figure out where they were plugged into. I assume they are why my needle is in the 3 o clock position- open ground, right? I can't find any obvious place to hook it back up!? So after building my entire truck while only doing searches for info and help, here I am asking a typical dumbass question. Any suggestions?
