I kinda checked mine earlier, wasnt getting 12v at the plug. Traced the wires ( red and blue ) along the roof to the passenger A pillar, they run down that to just infront of the door and into a white/clear multiplug. Unplugged it, no corrosion, those wires run up to the dash loom, so then i thought i couldn't be fucked anymore, so i fitted my harnesses instead haha.
