Headlight connector - cross reference?

[rborder]

I have a 2021 R18 1st Edition.
Previous owner swapped out to an aftermarket headlight - I am trying to go back to the stock light.
As part of the previous conversion, the harness going to the headlight was lopped off, with only 2 of the 4 wires used to power the aftermarket light. The other 2 were taped off and tucked back into the harness.
So, I'm missing the (bike side) connector, which plugs into the stock headlight.
I'm hoping to find it with a short pigtail attached, so that I can easily splice it back onto the factory harness.


My local dealer is trying to work with BMW to see if they can get the part.
I'd be very surprised if this 4-prong connector was unique to BMW R18 headlights. Does anybody know what else it might fit? Something easier to source perhaps? Ideal would be a cross reference part number to Doorman or something.
Alternatively, does anybody have a one of these connectors on a parts/crashed bike they'd be willing to part with?

Thanks.

Can anybody here post a picture of the stock plug to help me try to ID/find one? Also, if/when I find one, it will help me figure out which wire goes to which pin.

Following up - mostly in case somebody else runs into similar issues in the future and might find this useful.
The headlight plug can be sourced from BMW. Part # 12 52 7 549 033
You'll need 4 each, 12 52 7 545 858 and 61 13 8 366 245
All together, the parts were about $10.

It gets wired up like this (this is a stock plug, my repair isn't quite as pretty):


My stock headlight is installed, I've got a working high beam, and all my headlight related error codes are gone

Do you have the color diagram? Which one is high, low, I guess brown is earth and what about purple?

Attaching a wiring diagram that my dealer provided to me (I didn't find it terribly useful).

I don't think these headlights have the traditional ground/low-beam/high-beam setup. Rather, I think they have ground/power, and then 2 canbus signal wires that talk to the control module inside the headlight (that routes that power to the various LED elements). My bike was throwing errors, indicating it couldn't establish communication with that - missing - control module.

That's why the high beam would never work with my aftermarket light. The "power" was simply routed to the low-beam on my aftermarket light.
