Street and Performance 94-95 Stand-Alone LT1-specific harness, it was used for Dyno testing only, might have been used a max of twice and is in like-new condition. Its in the S+P catalog for $750 base price, might be $800 since its 4L60-E compatible. Basically it has 3-4 power wires that you wire into the car your installing it in and thats all thats needed. It has quite a few other labeled wires (fuel pump, tach, etc) for other various options depending on what all you would use. Its pretty self-explainatory once you see the labeling and it extremely easy to install. Its an ideal setup to use for installing a LT1 setup into an older car or street rod.

I also have a new PCM that came with the harness, M6 programming, tune is currently setup for 383ci LT4 stroker, 30lb injectors, and the GM Hotcam. The engine it was setup for made 525hp at the crank so its prob a good tune for that engine, prob not close for anyone else though unless it has similiar parts. Although its tuned now, I can have it put to stock but thats about all I can do with LT1 PCM's.

I would sell the harness for $500 shipped and include the PCM. If the PCM is not needed I could let it go for $420 shipped, which is about 1/2 of the new pricing for any stand-alone harness. The PCM alone is FS for $100 shipped.

New as-in its never been run in a car. It was bought from GM then tuned on the engine dyno. Its a 94/95 OBDI PCM.
