M30B35 swap wiring question

Post by brettreardon »

Hey guys,

We’re starting on swapping in a B35 from a ‘91 E32 auto, and had a quick question. Anyone who’s done a B35 swap with Motronic, are there any specifics that we need to know about the wiring? Are there any adaptations to make so we can use the E32 alternator, or do we have to use the E12 one?

Thanks!

A few here have done it, although I haven't. I'd look here for more info, E28s aren't the same as E12s, but are BMWs and share many, many things. http://www.mye28.com/viewtopic.php?f=3&t=60306
