Im having some trouble figuring out what I need for this swap and I’m having some issues with the car. I have a Z6 engine harness on it and idk if that might be an issue Bc I’ve heard people use a Y8 harness. I’ve also noticed the ECU wiring was all done by hand, so could the be a issue to my problems? My problems are my cluster won’t get my rpm’s nor speed, and after my car runs for a little bit it starts to idle up and down. I’ve cleaned the iacv and checked fuse 15 but nothing seems to work, I even got a new cluster. If anyone can help me with this I’d really appreciate it Bc I wanna get this thing on the road, it’s my only car.
