I want to find out what car my harness came from because if its from an e34 I want to extend the harness to make sure I can reach the stock ecu mounting point. Does anybody know the lengths of these 2 harnesses so I can measure and find out which one I have?
You don't need to extend or shorten either. You end up with a bit of extra worst case. But get a late model 318i ecu bracket. looks cleaner.
