Gonna try and attempt to do a 2.0 auto to 1.8t stick swap in my brothers mk4. So far I have
aww shifter box
aww engine harness
Brake and clutch pedal
plus various aww parts from donor car.
My question is can I uses the 01 ecu and harness into the 03 body harness. This would be going from immo 3 to immo 2, is that even possible?
I have heard of people doing the opposite immo 2 to immo 3.
