hi all, my first post on here, 2009 a4 b8 sedan exec sline, just fitted after market reverse sensors into the bumper. I have to connect a wire to the reverse light and earth, ive connected to the earth bolt on the body work but can anyone tell me the best place to connect to the reverse light. I've brought the wires up on the right hand side by the fuse box. Thanks in advance.
