can someone please help me find out if i have an obd1 or obd 2a motor? i kno ecu is obd2a but not sure about motor and tranny the engine and tranny are supposed to be a 96 but somethings on the motor and tranny lead me to believe otherwise usually the tranny would have a green vin plate mounted vertically,but mine has a white sticker on it,there should also be one on the block but dont see it anywhere was hoping someone can help me find out exactly what i have im thinking an obd1 motor and tranny with obd2a wiringharness and ecu.any help would be greatly appricated,date casting on clyinder head says 94 would that mean obd1?
