so... apparently testing power in the fuse box on this car isn't as simple as I thought.

1) Used a test light to check for power on / off when the ignition was on or off. Confirmed the accessory circuit I used is off when ignition is off via test light.

2) Connected everything, but the detector turned on then.

3) Stayed on w/ ignition, stayed on w/ ignition off.

4) What the hell is going on..

I've wired my E90 the same way and had no problem. I used the homelink slot on that though. But it showed the same symptoms with the test light though.
