Looking at at 01' z28 donor engine harness, but have limited time to remove what we need to get the engine to run in another vehicle ,

basically looks like all the engine controls go back to the PCM then into the firewall , I need to know where I can cut this off and still be able to rewire it into another car ( Mitsubishi Starion ) Please if anyone can help me out on this let me know, Thanks brudda's... Scotty
