There is no wiring up in the roof that will shut off with the ignition. I had to wire my radar into a hot wire which is always on behind the map lights. The powersave on the car shuts my radar off after a short period so it doesn't pull on the battery.


So you will need to run the new wire from the fuse box up to the roof and into your new mirror. And yes you can split it. 3 amps is more than enough for both items.

 

On my 04, I wired it to the sunroof motor wire harness. powers off after the key is turned off and the door is opened. Took me about 45 min (most of which was probing wires to find which was 12v with ignition)

 

does my car have powersave too? or is that part of some other wiring? (audio equipment, etc.) couldnt i just do an add a circuit to the accessory fuse? (so it would shut off like the cig adapter in the arm rest?) what guage wire do you suggest? 18? (i think like the end of the add a circuit) i was just going to use phone line w the bel detector and splice it in...
