Im thinking about swapping a ls2 into my truck and have a few questions. Would the truck harness plug into the ls2 engine harness? Not sure how the harnesses are on the ls2 or the lq4 are but if it is similar to the fwd v6 cars the ecm is in the engine harness and wouldn't have to do anything with computer wiring. Ive done l67 supercharged engine swaps on fwd cars and its plugin and switch a few wires at the firewall plug and learn security system. Would it work out that way or be allot more work? It's a 4l80-e 4 wheel drive not sure if the computer would be even compatible with it? Any thoughts or help greatly appreciated!
