do it yourself LS2 harness conv.
#2
2. call John @ Speartech
3. tell them configuration
4. pay the money and be done.
No seriously I had speartech build me a custom harness for my LS2. You can modify your harness but it will take some research and a lot of time. A guy a my work did it with an LS1 going into a 91 camaro.
