What is the small plug in the picture for or to?

This is a 91 318is M42 harness.
Its a small 2 wire plug in the glove box with the DME that goes up under the dash.

Is that the plug for the flashlight? The rechargeable one?

Fairly sure it is - when I plugged my flashlight in the socket looked identical

[MonkeyMadness]

Wat? o_O
No this plug was plugged in to some wire that snake up undet the dash.
It wasn't just a dead plug hanging there.

I just need to know whats on the other end of the two wires that snake up under thw dash.

I don't think so. I'd have to check the ETM, but I think that is how the A/C idle speed and road speed signals reach the DME.

I was swapping ECU's around a couple days ago, and I noticed that there was a black plastic unit like that next to the ECU in the '88 vert and '91 sedan, but not in my '87 sedan. I was actually going to ask what it was, but....here we are. I could take pics tomorrow if it helps.

I cannot see the colors of the wires, what are they?

Black w/ white strip

Light purple w/ white strip

The 24v swap guys that actually managed to keep their AC know this plug well when it comes to trying to keep a smooth idle when you turn the AC on

WTF !!! , Guys This Plug Is For The ECU RPM Control for The AC Compressor .
It Comes With a AC Cold/Warm Kit .
I Have This Plugged In My Car . and If you Remove it The RPM Will Go Really high When you Turn On The Cold AC .
