I have an Eclipse Sat Nav installed in my 2006 TDI Touareg. I had someone install a rear camera when I was away on holidays and since then the screen does not dim when used at night when the headlights are on. On pulling the Sat Nav from the dash I noticed the illumination wire has pulled out of its connection and I cannot find where the wire goes. Can anyone tell me the colour of the wire that would connect to the headlight on position? Thanks.
