M50 wiring crash course

[02stu]

Can anyone tell me what wires need to be connected to make the m50 plug up? I have a non-vanos engine thats in a 91 318is. Thanks

[Addissimo]

e34 or e36?

I dont have the wiring diagram for the 318 unfortunately.

I can supply you with e36 & e34 information though.

I swapped a 95 M50 into my 91 318IS. I wired the harness myself and had no problem with the wiring. I followed a slightly altered version of the AKG motorsport diagram. Started up fine the first time

Wow, awesome writeup of the wiring.

I'm assuming that is the wiring diagram for '86 and up m20s, correct?
('84 and '85 had a slightly different wiring diagram.)

Oh, nice write up. With color coding and everything. Damn that's nice. Thanks for that info!!

thayat is corrayect...

if anybody has the different wiring diagrams for the 318i(s), and early 325i I'd love to put it up on my website.

PM me please.

Thanks,

Yeah now I see...you're that much closer to being a pimp.
Impressive. Um, but your first attempt at the wire harness puts you down two rungs on the pimp scale....that one was a doozy.

Addissmo that website is going to make swaps so much easier. Unfortuantly I have a 318is and a non-vanos engine so I need a little more help. Anyone have the wiring diagram for the non-vanos engine, or the m42?

[Addissimo]

wiring for the non-vanos is the same, the vanos system lies in the ecu and wiring harness, it has nothing to do with body electronics, or the wiring bridge you're making.

As far as the m42 differences... I don't know. I'm working on finding out though. Hopefully somebody can chime in on this sooner than I can.

That makes since, but I don't have same wire colors that are in your chart. So maybe its just because I have an early engine.

[Addissimo]

wait... how are you doing this wiring project?

Are you splicing the acutal engine harness into the main body harness? Are you using an e36 chasis plug and an e30 wiring harness plug? I'm a bit confused as to why you're worried about the colors of the wires on your engine harness. Worry about pin numbers instead.

I'll go to storage today and see if I can find my cds with different plug layouts on it.
