Need help asap. Replaced a factory headunit today. It was a factory single DIN underneath and a tv screen on top. Now it just has a D/DIN headunit. Everything works fine but everytime you turn the lights on it blows the brake light fuse under the bonnet.
There were three wires left on the plug that had the power, grnd, acc and front speakers. One wire is yellow and the other two are black(the black wires run into the same point on the plug) My guess is this is an illumiation wire for the old headunit and the 3 wires have to be joined together to complete the circuit and stop the fuse from blowing.
Need a reply asap. tonight would be good.
Thanks all
