Thanks for the note back. I will look again under and behind the tow hook opening. I have looked and felt that whole area and the only harness I can find I think is the fog lamp harness. Is the wire for the heater cover in convelute or is it a plain plug wire? The wire coming off the oil filter housing is red. The only red wire that I can see coming from under the engine is the postitve battery cable on the drivers side. Thanks again.
