So I am starting to plan a m42 swap into my 86 325e. I have the engine, trans, radiator, drive shaft, engine harness, and DME. So I have been doing a lot of reading but this isn't the most common swap. What I am getting confused with is the wiring. I have the two pin outs but the thing that is throwing me for a loop is the c104 plug on the early model. Should I just do something similar to this http://www.r3vlimited.com/board/show...ghlight=86+etm? Any help would be greatly appreciated.
