Taking off the kick panel above the pedals and beneath the steering column, I have a huge mess of wires. It looks like I have some sort of BMW alarm system:

There is this plug coming out of it:

Which plugs into this connector from, what appears to be, the wiring harness for the car. It looks like this connector goes into the panel behind the speaker, so it may be locking stuff, or maybe the door switch. Notice the stray brown wire. I tried grounding it, no real effect, so I tried wiring it to what looked to be the missing spot in the connector and attached it to the brown / yellow wire from the above pic. That didn't do anything either.

Finally there is this connector that seems to be from the wiring harness, but the colors don't match the other wiring harness connector of the same size (pic above this one):

Really, I'm discovering all of this while just trying to get my check panel "brake light" indicator to turn off. My brake lights work fine. Sometimes it will be off, especially when it is super cold, but when the car warms up it will come on. Otherwise it is on all the time. Also, randomly, my left turn signal will flash fast for a bit, then it will switch back just fine. All of the bulbs are fine.
Any help would be appreciated.
