Have just installed some parking sensors but the main unit is not receiving power.
I have wired it in to a reverse light bulb with the red wire (from the unit) connected to the red & yellow wire which goes to the middle of the bulb and the black wire (from the unit) to the black wire which goes to the outer edge of the bulb.
I used snap on connectors to join the wires.
The bulb lights up when reverse is selected.
Anyone got any suggestions? Not rude ones I hope!
