I have an 83 drop top I bought new, it has only 3800 miles on. It had no balls so I never drove it , few years ago I built a roller block 302, and swapped out the original 3.8. I used most of the original wires and all original sending units for a 302, I have the original dash electric gauges(don't work) and some summit gauges on the cowl (these work) My problem is that I want my original gauges working especially my gas the gauge, So I have new sending units and have used the original wires, (except for the v6 wires) but they don't work ! any Ideas what I may have done wrong ? thanks john [email protected]
