Need Help Identifying Plug

[kid8]

Hi Everyone. I tried searching and didn't have much luck finding anything. I'm in the process of installing a new to me dash after not having one for several months. I had everything labeled, but apparently this one fell off at some point. I thought at first it was for the glove box flashlight but the wires were still connected to the base.

Does anyone know what this plugs into? It is near the HVAC box. It is a black 4 hole plug with 2 wires in it. They are black/violet and black/red. Any help would be greatly appreciated.

Sorry for the bad pictures, ran out of light:

There are a lot of unused plugs all over the car. Might go to nothing.

Yea, it might not. I could have sworn I had it labeled at one point though.

The car is an 89 325i if that matters.

Thank you so much for the help! I think this explains why I couldn't figure out where it connected. I have a swap and a different ecu. I'll download my ETM and dig in, thanks again for the help!
