1981 M535i (E12) - Wiring Diagrams

Post by DKoh »

Hi everyone,

I'm new to the FirstFives forum. What a great resource for all things E12!

I have a 1981 M535i with some electrical problems and I'm wondering if anyone on here has found a wiring diagram for this specific model. Anything from UK or South Africa will help. 1980 - 81, E12, M535i.

I'm having issues with shorts and I'm guessing it's the ECU harness.

Any resources/suggestions will be very helpful.
Glad to have found a community that is so resourceful!

All the best,
Doug

Welcome to the forum here Doug.

What kind of electrical issues do you have? And do you have the RHD version (because you are referring to UK and SA)?

The wiring loom is - as far as I know - not M535i E12 specific and should be exactly the same as other big 6 cylinders E12's (528i). Although there might be differences between the US and European version. Did you check the Haynes manual? I think an electrical scheme is included.

Also, if you haven't done so already, you should join the M535i E12 Yahoo group.

A scheme should also be in the owner handbook /. user manual.

Have you checked the e24 manual? It's my understanding they're close: http://www.malloc.nl/BMW/635CSi/pages/en/index.html

Could be wrong, but if nothing else, it's another link for you. Good luck!
