Hi All,
I am looking for help with fitting some rear parking sensors to my 2008 S4.
The process is simple enough, Drill holes into bumper, with provided hole saw. Run wires upto control box and plug beeper in and mount using sticky tape
.
My problem is, the control box is designed to get power from the reverse bulb wire, s that when you go in reverse the sensors turn on.
So my question is how do i figure out which wire is the reverse bulb.
I have had a look and all the wires are different colours so i would imagine there should be a diagram somewhere to tell me but i cant find anything?!
Any help would be appreciated
