This angle shows that BMW actually did wire in the US fuel pump relay trigger (black/violet wire). They made it easy for us!





I think I might order this. Gotta love how BMW made the harnesses fairly modular on these cars.

To restate the part numbers:

6MT:
12517831649 -- Upto September 2003
12517835524 -- September 2003 and beyond

SMG:
12517831652 -- Upto September 2003
12517836372 -- September 2003 and beyond

Don't ask me what the difference is before and after 09/2003 -- I have no idea. This part includes DME connectors X60001 and X60002, and the pin outs are the same for all years at those connectors

Where are you sourcing the harness? Tischer is quoting $215. Is that cheap? We could order those clips too, they are only $0.70ea

That part number includes this whole thing:


That includes DME connectors X60001 and X60002, as well as a few miscellaneous connectors that sit in the Ebox, and that large plastic cradle is what DME sits in. X60001 is the connector that actually powers the DME. X60002 is mostly for the O2 sensors, but there are a couple miscellaneous things there as well.

The fuel pump relay concern I had was because US and Euro cars have the fuel pump relay trigger on different DME connectors. US cars have it on X60002 (which this part number includes); Euro cars have it on X60004 (which is the connector that goes to the rest of the vehicle harness).

The way it works on US cars is that fuel pump relay trigger goes from X60002 to a small connector in the Ebox itself. The connector in the ebox goes to the rest of the harness. Euro cars have no need for that wire since their fuel pump relay is wired differently. BMW was nice enough to leave the wire installed for us anyway, at least when ordered as a replacement part.

I'm ordering it from husker parts -- ends up being $215 shipped. No idea how long it'll take to come here. Honestly, that price is better than usual for BMW's harnesses. I do have plans for the original harness anyway

I will. It's easy enough though. If you were able to reroute the O2 sensors, you'll be able to pull this harness.

Strike that, dealer just emailed me saying the harness was discontinued.

Also possible that US dealers are simply blocked from placing the order. Maybe I should try ECS
