What is this wire? It is heavy gauge and comes through my firewall by itself just above the hole where the wires/harnesses for gauges and wiper motor come through. It has a push connector on it before it terminates. Someone had it hooked up to the starter side (not battery side) of the solenoid. Even though everything is working, I'm sure this car has some wiring anomalies. The car was quasi restored by previous owner about 25 years ago.
