Canbus/tipm issues on my swap before motech stepped up and rewired/reprogrammed= headlights/brakelights, wipers, charging system, alarm, radio, accelerator. Prndl, air conditioning, door locks. The crank sensors worked ok. So, if none of that matters you are ok. I had sensor issues with the coolant sensors (jeep vs gm engine coolant. The jeep sensor kept insisting I was 280* when I was under 220). The ls sensor told the engine it was ok, but the jeep sensor told the warning tone to go off continuously. This was a gen 3/4 kit from 2011 and Motech had different wiring and different grounds from the next gen. Before I took it to Motech, it ran, usually, but it couldn't be trusted. The instructions in 2011 were shitty. I made some mistakes in the harness, and my mechanic made some more. Robbie redid the entire harness and changed the computer. It worked fine after that.
Those were what I remember, there were some other issues, but i can't remember what they were, throttle and position sensors, and fan cooling, were a couple but they might have been actual hard part issues.
Can you do it with a paperclip and a clothespin? Sure. Go for it.
I am a troll. Do not take my advice. It isn't going to help.
