Hey folks!

I have a 2015 Mazda3 s GT, 5-door. I'm adding a dash cam. I have the cable to hard-wire it for power. This also has a rear camera (more about that later) so I will be running a wire along the windshield and through the side of the dash trim but I am sorely tempted to access the power I know I can find in the roof console instead of running under the dash to supply power to the camera which is mounted behind the rear view mirror. Has anyone removed the ceiling console where the lights and sunroof controls live, in order to tap into a switched 12volt source? This particular wiring harness will take up a considerable amount of space under there since it has the little adapter box at the end of about 12 feet of wire, but I feel sort of certain that there is enough empty space up there so I could stuff it all under there, but would it be worth taking that stuff apart in search of 12volts?

If that is unadvisable for some reason, like I said, there is also a wire that will be routed to the rear window camera so I'll be routing a wire around the windshield and down the side of the dash anyway so if it's just as easy (or easier) to access power under the dash, that's not a huge deal. If so, is there an easy place to hook up under there and should I go down the right or left side of the dash?

And speaking of routing to the rear camera, well, I haven't yet inspected closely for a good route to send the wire. Before I get into that, are there any recommendations from experienced installers here as to how I should go about routing a wire from behind the rear-view mirror to under the third brake light on the inside of the back window? Any particular route I should pursue or avoid?

Thanks a lot!

I have front and rear cams (Blackvue) and are powered by the BLackvue power magic which ive located behind the kick panel and just run the power up inside the a pillar trim (pull door seal and poke wire in) and the across the front of the head liner to the mirror plastic cover then drill a small hole to allow it to come out and clip into the camera.

The wire for the rear cam I just ran along the top edge of the headliner (pull door seal and poke it) then behind the plastics at the B post and C post behind the headliner to the rubber sock that feeds wires to the rear hatch and then to the cam.

Full install took me about 30 minutes.

Thanks, I'll take that to heart. Which kick panel (which side) did you burrow into?

That's interesting. While I don't plan to mess around with the backup camera at all, I might have to dig into those rear hatch panels. Thanks.
