Z3 EV wiring help: instruments and ignition

[Tom Cheesewright]

Would appreciate your help on a couple of things. Wiring up my EV now (see project thread for updates) and trying to find out:

- Is there a signal line that runs from the ignition switch to the DME, or to the area where it is located? There must be, right? But so far me and my multimeter haven't been able to find one. And my DME connectors seem to be wired completely differently to the pinout I have found, which doesn't help (car originally had an M43).
- Where does the wiring for the instrument cluster pass through the bulkhead/firewall? Is it in the main fuse box surround? There seem to be very few wires that go out of the black surround where the DME sits that don't go to the engine.

Any help appreciated.

Thank you. That's about the third different set of wiring diagrams I've seen and a) totally different to the ones I have and b) looks much more useful!

Here is a wiring diagram specifically for the UK MY2000 Z3's. It has the engine management diagrams for the M43.

Fantastic - thank you.

EDIT: Thanks again - looks like this was just what I needed.
