Mystery connector on E34 M50 OBD1 harness

[radr]

I bought the car swapped and I'm going through to clean it up now. I've confirmed via part #s that the OBD1 harness comes from an E34 M50 car. I found this connector hanging out in the same area as the DME connector but I can't figure out what it is even with wiring diagrams. Does anyone have an idea?

Jeez I should know this one but can't remember.. was the e34 harness your using from a auto trans.?

Where do the wires lead to?

I’m not sure if it was an auto E34. I found a thread on here mentioning the trans connectors are separate in the E34 but not 100% on that.

The brown wires lead to the main ground (makes sense) and the others go into the mess of wires leading to the rest of the engine.

Did some more digging through the diagrams. I believe it's x6003 which is related to the auto trans. All the colors match up with an M50 A4S-310R car, the weird part is the diagram lists the connector as black, 8-pin when the one I'm holding is a black, 12-pin with only 8 of the pins filled. But I can trace all the pins back and they match x6003.
