Good luck.

Bill,
The original 4.6 harness is back in the truck along with the PCM, which has the code: GKW3 and part #: 2L3A-12A650-GD
There were literally 3 other PCM's that he tried to get to work and I have their numbers too.
I don't know if you looked at the link with specs of the engines from years '97-'01, but this mechanic seems to think that the differences in HP/TQ on the stock engines from those years are solely from tuning and nothing else. Is there any truth to that? He tried to promise me that all these engines produced the same HP/TQ and the differences come from the factory tune.
