Just wondering if anyone knows how to make the Aux power/Cig lighter in the dash turn off with the truck?

I don't want to do this to all 3 of them, just the one that the radar is plugged into.

Thanks...

I went to my auto parts store and bought a pig tail adapter for 12V accessories and wired it in under the dash to an ignition wire and ran the radar detector wire behind the plastic front that goes around the radio and A/C controls. This way I don't have to worry about seeing the wire all the time and the radar detector turns on when the key is turned on.
