I will be changing out the motor in the beater soon and could re-wire it for Motronic 1.3. Have a harness from an 88 with the quick disconnects and the crank sensor, but here are the issues I have identified so far:
1. I do not have that toothed wheel for the crank sensor! Can this be added?
2. What to do with the flywheel sensors? Do I need to replace the tranny bellhousing I just repainted, or just plug the holes?
3. How do I deal with the fuse box? The new harness has a round connector vs. the square one.
4. Anything else I need to know before I commit?
Reason I need to decide now because the fuel rail has the quick disconnect for the injectors, so I have to decide which one to use and the crank sensor should be added before re-assembly.
TIA

1. 325i harmonic balancer can be added, but I think it requires a new V belt for water pump and alternator as the pulley is of different circumfrence.
2. I'd probably cut the wires and leave the sensors plugging the holes, but im sure someone else has figured out a better alternative.
3. What year is your eta? I have the square fusebox also and im looking for a super eta E28 harness. Ive been told that its easiest to use that combination and to splice all of the wires just outside of the fusebox. If I can find a wiring schematic for both, ill send it your way as Im going to need the same.
4. You'll also need the 3 wire ICV, 325i throttle body, intake manifold, maybe 325i afm, etc. Which injectors are you using?
