Re: LS1 swap harness
Can you make one for a 92 Z28 LS3 with a 4l80e? How does it interact with the cluster?
allen.bray64@yahoo.com would you need my motor or dash harness?

Re: LS1 swap harness
Very interested if you can add A/C. I have a 91 Z28 with all the specs mentioned above. What is the MAF truck 5 wire? And what else would I need to make it work with my gauges, speedo and engine light?

Jon's harnesses are the way to go. I've bought two of them from him and couldn't be happier. Bump for an awesome guy/wiring genius.
