Factory alarm brain location? Short background on the situation:
My O2 sensors started going crazy out of the blue and my factory alarm somehow re-enabled itself*, so I'm pretty sure I've got a bad ground somewhere. I'd like to know the location of the factory alarm so I can start tracing down the circuit to find my issue. I know the shock sensor is on the passenger side fender well in the hatch, but I need to know where the brain itself is.
Thanks in advance.
* The alarm goes off if I lock the doors by the remote, and if I lock the doors by the electric lock button it goes off when I shut the door.

Thanks Mike, that helped me get to the next step in my miniature mess.
Next question, which wire from the BCM goes to the Gauge fuse in the fuse panel? The owners manual shows that the "Gauges" fuse has the BCM on it, but the other BCM features seem to function just fine. So is it safe to assume the power for that fuse's power comes FROM the BCM? I've got the pin-out for the BCM, but I don't see anything that looks like it goes there.
