If you want a cleaner look and wiring made for that engine, go with the b35 20-pin.
either will work. I prefer the m30 harness since it looks nicer.

I think he's got a late model e30, so no connector needed in his case. Other than maybe running a wire or two for tach and/or check engine light.Mtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

im running my 89 325i harness on an 89 e32 b35. I think the easiest way is to use it and just to extend a couple wires in the engine bay (crank position sensor, and tps i think, youll see when youre in there). the b35 computer fit perfectly in my harness and she fired up no issues, everything works on the dash, no need to run any wires or make any adaptors.

One step closer, we got the engine out of the donor car and the rest of the car parted. moved them out and moved the white car into position. i have a few other projects going right now but this one will be done right and have some special touches. will probably debut the new set up at the 2010 picnic. watch out!
