Here are the pinouts side by side.
E28 Harness, MS3, MS3X.pdf
if anyone here has ever wired up ms3 to the stock harness would you tell me the thing you had to change?
I know I have to change my tps to a newer m30b35 or m50 tps as they use a signal throughout from closed to open instead of just wot or closed
as for the injector stuff, do I just wire the ms3 2x injector control 123 to the injector control, single wire, 123 on the stock harness? and the same for the injector control 456?
