Note- When you hit the unlock button the radar will turn on because the car gives power to that outlet.
Just as a follow-up to this suggestion, I also "hardwired" my Bel RX-65 from the outlet in the passenger footwell. I actually modified the Bel's cig lighter plug-in adaptor and then ran the wiring around the footwell to the door seal, up the A-pillar, and underneath the headliner (see below for some pics).
I actually chose this solution so that I didn't have to "mod" any of the vehicle wiring (tap into wires, etc.). Works great and it was pretty easy.
Let me know if you have any questions!
