I was wondering if you could swap a J-spec S5 T2 wiring harness directly with a A-spec S5 T2 wiring harness on an A-spec car? Do you have to do anything because in a J-spec car, the ecu is on the left side and right side on A-spec car? Does it plug directly into everything with no problem and will the A-spec ecu work correctly?

 

it might not reach, if it does reach it will be close. you maybe have to move a couple wires around

all the wires reach i dont know about the plugs though cause im doing the same thing but its s4 to s5
