1997-2007 GM LSx style PCM connector seals. Two seals are needed per each PCM. These parts are used and will show signs of age and use. Dirt, dust, grease may be present.
I used this product on a ls swap. Plug and play. One thing I would like to advise is ask questions. I bought a CPU before this one and it was programmed for drive by wire meaning a electronic throttle body. The one I needed was a CPU programmed for drive by cable meaning it has the physical cable that is attached to the gas pedal. This is my first build and I didn't understand the difference. Like I said, ask questions. They will respond. Thanks
I set this motor up to start on a engine stand. Not my first LS swap I wanted it running before I use it .I had a few little problems with engine not computer related . once I got the old fuel out of injectors , starts right up and sounds good . For the price it is worth it , when I do next one I will be buying another one from LS solutions
