I've installed a rear camera with a mirror style display which replaces the rear view mirror.

Running power up from the centre console while keeping the cable hidden is difficult. But i have the headlining out for a leak repair.

I've bought a 12v to 5v step down module I can attach to the roof somewhere near the courtesy light and sunroof motor (which I'm about to replace). Butchering a USB cable to expose the Black and Red wires was easy enough.

I'm looking for an ignition fed 12v supply for the input. Since the electrochromic rear view mirror was already disconnected when I bought the car that seems the best option.

Anyone happen to know which wires will give me ignition switched 12v and GND?

White/Pink has ignition switched power while Black is ground. Power comes from F6 which is fused at 10A. I've run power for a dashcam from the back of the fag lighter socket, it goes across under the steering column, up the A pillar between the plastic trim and door rubber and can then be tucked up behind the headlining without having to remove anything other than the knee panel.

Okay. There's actually room inside the mirror for the step down unit. No pink and white wire, but there is a red one. Do you reckon that's it? ![enter image description here](https://photos.app.goo.gl/nEV2yofQpHDbdEnT8 "Video Mirror")

Edited it so your pictures show. Those colours appear to be on the actual mirror itself and not the wiring that goes to it. Although it does appear to have too many wires. The ETM shows 5 wires in a black connector that plugs into the top of the mirror base where it is fixed to the windscreen.

Exactly what I did.
Don't know about a permanent live up top though.

Don't need a permanent live I'm not using the crash cam motion sensor for anti-theft. I'll sort it with my multimeter and report back. Thanks people.
