I do know HPF got two pro-EFI system to work on two Z4M's.

Well, the DME is completely different, which is the thing. Interestingly, a lot of the wire colours are actually identical. It makes some sense considering that the engine-side loom is identical, wouldn't have made any sense to assemble that side differently. That being said, I've already encountered a couple of oddities in the DME loom that strongly suggest assembly-time adaptation of the harnesses. Which is kind of cool.
Started by disassembling the DME connectors. They're actually a handful of connectors inside a housing, so a little screwdriver and a few minutes and suddenly things are a lot easier to work with:
Started with the coils since I'm not just adapting the harness there, have to put the ignitors in the mix. I figured this would be a reasonable place to mount the ignitors:
And then got everything wired up:
And that's as far as I got so far today. Protip: try very, very hard to use similar colours when mating a factory harness with a new harness you're building. Because I was doing that, I caught a mistake I made in the wiring diagram (yes, I am keeping as-built notes and will update the diagrams later on). Took 5 minutes to straighten out instead of the hours of diagnostics it would have cost down the road.
Phew.
