1989 Chevrolet Truck G30 1 ton Van 5.7L FI OHV 8cyl-Motorhome Chassis. I cannot find where this hooks up under the dash. I tried to track it via my wiring diagram but go totally confused. TIA.
If it wasn’t hooked up when you took the dash apart, it’s probably not in use. Could be an option from the factory that wasn’t installed or it could be a circuit that’s been bypassed due to a short.
