When I was sat in th truck with everything turned off, I would hear a cvery faint lick every 20-30 seconds come through the cargo area speakers (which were left connected for OnStar). The stereo was draining the battery flat over night.

I don't have an aftermarket stereo. But I have heard something that sounds like a faint periodic (every ~30 seconds) clicking in some of the speakers with the vehicle off and stereo off but when RAP power is still in effect. So perhaps my stock stereo is still to blame even though it's supposedly wired up right.
