I own a 92 Chevy 1500 extended cab 2wd with a 5.7 engine and an automatic transmission. The truck once had a standard tranny and Im not sure that this is the original engine.The plug to my automatic tranny does not have any wires plugged into it.There are a few loose wires hangin around under there but they have no plugs.Does anyone know where I can find a detailed wireing diagram for a 92 chevy other than the ones in the Haynes manuals?:confused:
