I hate hanging cords from radar detectors, so I spent some time this afternoon installing a direct-wire connection and mirror mount for my Valentine One in my Mazda5.
I planned on tapping power from the overhead console, and with a sunroof, it was sure to have a powered-only-with-the-key-on circuit, if I could find it.
First step, pop out the overhead console unit, like you would for changing out the map bulbs...
I used my continuity tester to probe on this main connector, looking for a power-on-key circuit...
Found it...this particular black wire.
Straightforward install per the kit: crimp on their tap; drill and place a screw for the ground; then, test it before putting back together.
There's a nice space around the console to stash the wires, and a nice gap to feed out the connector to the detector. I used this inexpensive mount from Amazon.
No trick getting it mounted on the mirror, and adjusted mostly out of the way...seems pretty solid.
