Hello, long story short I bought a rolling shell and a motor for what I thought was the correct for the wiring harness/ecu, i have a evo 8 motor and come to find out I have a 9harness/ecu. Is it possible to use it or do I have to buy a ecu/harness to match? This may be a silly question but would like to ask if anyone has any information that would be helpful. Thank you
