@Sean d The attached wiring diagram covers Z3's from 4/99 on wards.
If you are researching the 3 wire cruise control switch matter, you'll see in these diagrams that a three wire hall-effect switch is used to give a signal to the DME (6571.0-3). The issue is that the early M52TU powered Z3's got fitted with a 2 wire switch before the 4/99 mods got through to the factory floor. The 2 wire switch gives the DME a signal that was opposite to what was needed e.g. It said the clutch was in when it was actually out, so the cruise control would not turn on and hold speed.

The health warning on the link warns you that the wiring diagrams are for NA cars and may not be 100% correct.
The diagrams are all in the resource section

Have tried that site but does not seem to bring anything up. I just get a blank section where the diagram should be
you have to run java,
my first screen on opening that links shows this below:
should be a link in left hand side to click on and run java, which then opens the drop-downs on the LHS in a blue colour. then I can select any diagram.
