Question for the S50 swap experts...
I'm in the middle of an S50/5 spd build on a 92 E34 525iT. Was comparing the harness that's on the S50 and the harness on the M50. On the engine side of the harnesses, looks like the only difference is the oil level sender connector is present on the M50 harness and not present on the S50. Also the Vanos connector is present on the S50 and not present on the M50. Now I'm also looking at another M50 on a 94 525iT which has vanos, so obviously the harness has the vanos connector.
So the million dollar question.
Could I take the engine harness of the 94 525iT with the vanos connector, put it on the S50? If I did this, I think I'll have a home for every connector on the S50.
Also I never quite understood why you keep the DME of the M50 and just change the chip when you do an S50 swap. I would think if you had the DME of the S50, that would be the proper DME to use.
Any insight would be helpful. TIA.
