Switched 12V for radar detector
Please forgive me if this has been posted before; although I didn't find anything similar.
I just got a Bel 985, and thought I could hook it to sunroof/dome light area. I found the 12V and ground, but that would mean the detector is on all the time (including when the ignition is off). I'm concerned this will drain the battery.
According to my voltmeter, there isn't a source of switched 12V up there. It seems both the sunroof and dome switch actually switch in the ground, rather than the 12V.
Anyone have any info?
