Have a problem. I’m new to this. I have 99 Honda Civic ex coupe 5mt. Someone broke into the car and cut the harness and took the ecu. So now I’m stuck with no cabin harness. I know I can use a 99 to 00 civic ex/si harness but those are hard to come by now a days. Can I use a cabin harness from a 00 Honda Civic ex 5mt sedan?? Or does it have to be from a coupe?
