Hey guys I've been reading a lot about the wiring for an s52 swap in an e30 but I'm having some misunderstanding with some things and can't seem to find any info on it
1: There are 3 connectors on my engine harness, x20 x69 and x6031. Everyone talks only about the x20 conenctor but what do I do with the wires in the x69 and x6031? Theres only a 4-5 wires in one of them and another 6-8 in the other one.
2: The engine coolant temperature sensor, I have the correct brown top coolant temperature sensor but where do you plug this in at? I have it installed where the coolant lines to the throttle body go but obviously there was never a connector nearby for it. Do I need to run an individual wire from this to the c101?
3: Where can I get a grommet for the ECU connector as it travels inside of the car?
4: check engine light, how do I wire this up so it works? My car is an 88 m3 and never came with a check engine light from the factory of course. '
5: oil temperature gauge, anyone have any info on how this is to be wired up to an s52?
