I'm just finishing up installing a new front wire harness from Vintage Wiring of Maine. Everything seems to work but I do have one problem. When I go to start the jeep and press the foot switch and release the starter stays engaged and running. When I turn the switch off and back on the starter kicks in without pressing the foot switch. All switches have been replaced and tested. I even tried putting in the old switches with same results. I retraced all wires and are in correct locations. So here's the interesting thing. I traced back to a oil sensor switch, not the oil pressure, and not sure what it does. Two wires, number 77, and wire 77B got to this switch through a plug.
When I unplug from the switch everything works fine. So I'm at a loss of what to do next. Is the sending unit the problem? Do I really need to have this plugged in? I need your help. One more thing. It ran fine before I changes the wiring harness but wires and connections were questionable.
