Backround: Looking to run KTuner (Only works with 05-06 ECU) with my 02-04 engine harness and K20a2, without buying a conversion harness. I've been told repining my 02-04 harness to function with the 05-06 ECU is possible. I don't know much about wiring, but know how to depin a plug, and know how to take my time and label everything.
1. Is there anything else I'm missing? Is there anything involved beyond just moving around pins in their respective plugs?
2. Where can I find the wiring diagrams so I can begin to determine what needs to be moved and where? Also any helpful FAQ's would be good.
3. Anyone done this before?
