s52 swap questions
 

hey Guys
I have been a Subaru guy for a long time but last year I sold my STI swapped 99 RS and bought a 1997 318i with auto transmission(long story). The transmission is starting to slip and it is painfully slow so I did what any car guys does, purchased a totaled 97 m3 sedan with 5 speed. I have the small issue of EWS II to work around. My donor has no key, so my plan A was to take the vin and title to the local bmw dealer( 70 miles away unfortunately) , buy a key and swap over the ignition switch, ews, dme, gauge cluster and engine harnesses and I am done with wiring.

However I have the issue of my 318 being an automatic, therefore my chassis harness is not wired for the clutch switch

Here is my question for the experts. Can I just simply swap engine harnesses, ignition switch, ews, dme, and jump the range box switch?

Aside from the issue of the clutch switch am I missing anything else?

I would prefer to not have to swap out the chassis harness. I had to do this on my sti swap in order to have the JDM sti and usdm harness merged and boy did it suck! I can only imagine the bmw chassis harness is a whole lot worse to remove.


Thanks for the help in advance.

edit: looks like the range box switch simply replaces the clutch engagement switch so I should be able to just jump the range switch or wire in a momentary switch some where for security

One thing to note, swapping the ignition isn't necessary for EWS swaps and alignments
