 S52 obd2 swap wiring help
Hello everyone I'm new to the forum. I need help wiring my s52 obd2 swap. I have a 1997 318ti manual and my donor car is 98 m3 sedan also manual. My 318ti only has 2 main harness connectors and the m3 came with 3 connectors. I originally thought I can just plug the 2 connectors in and it would fire right up. But that's not the case, now I'm stuck and not sure which pins need to be moved around. Any help is greatly appreciated. Thanks for reading. |
