Has anyone documented a good switched 12v source to tap off for low current items? I'm mounting a radar detector off the rear view mirror. I have an SE with no sunroof and didn't find anything great behind the headliner/dome light area after taking it all apart. Just the power connector for the Info/SOS module, microphone wire and a 4 wire connector running the dome and dimming function. The dome light connector does have what seems to function as a 12v switched wire on the end but it's not run by the ignition, rather on and off as the car is armed or disarmed.
My usual wiring diagram source doesn't have anything on this vehicle yet. Thanks.

I think I tapped into the fuse box to one of the USB port fuses.

Here are some pics from adding extra 12v power to the dome light area. I ran a power wire through the headliner and down the driver side A-pillar into the fuse box. Mounted a double spade grounding tab and a second grounding screw behind the dome light assembly.
I've seen posts wondering how to remove the A-pillar panels, hopefully these pics will help. Use caution, patience and then force.
