So we just completed the painless (ha ha) wiring install on the 1970 Bronco. Finally got everything to work. EXCEPT the gauges. The oil gauge PEGS to 90. The AMP gauge is 0 or negative (maybe loop the other end of wire?) NO Fuel reading NO Temp gauge.

Replaced the temp unit, and Oil sender, and fuel tank with new sender.

Lights work on gauges and everything else seems to work.

Is this just Ground issue? or is there just something else going on?
