I have a 1978 C20 that I had a body shop swap onto a K10 Frame. I ran into a couple of smaller issues but one i cannot figure out. The body shop cut the wiring for the dual tank switch and I cannot figure out where I am going wrong. I have put in two new sending units and they are grounded properly as well as a dual tank switching solenoid. I believe the switch works, it worked before the swap.
My main issue is I cannot tell if it is actually switching the tank and my fuel gauge isn't working. Can someone direct me to the wiring for the fuel guage on a 1978 C20 as well as the switching valve wiring? The fuel gauge not working is driving me mad. I have a round 4 spade connector on the firewall.
