I'm trying to install a pair of USB sockets in the ceiling behind the front interior light assembly to power a dashcam. Not fussed if it is switched by the ignition & I am trying to avoid running a dedicated wire down to the fuse box.
There is an unused connector with 3 wires lurking up there & I wondered if anyone knew what it was intended for. Pic below.
The red wire has 12v which fluctuates on it & the orange is a steady 12v. Both voltages rise when the car is started.
