Hey guys new here and hoping someone can help. I bought a 85 Monte the guy changed motors and put a 350 with a carb set up. Now my problem is my gas guage does not work and my understanding is the car needs its original fuel relay to work the guage and the guy hacked the whole harness almost to the firewall and I have no idea which wires went to the relay. I did a similar swap on my 91 camaro and just plugged in my relay and I got my guage back. So I'm hoping someone can tell me which wires went to the relay? Or is there another way to get the guage to work without the original relay
