Has anyone used this new modular system? It's pricey but quiet complex. I'm thinking of using one to rewire a 56 Chevy pickup project that uses a donor 2005 GMC Envoy XL motor and drive train with a special wiring harness to control Engine, TRans and Tranfer case. Any comments welcome.
Since you are going to be running an LS series engine I would post over at LS1tech, that would be the place to find the info. I have read about the system but so far I have been modifying factory harnesses for my late model fuel injected drivetrain swaps.
