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?
