Hi all. I am literally at my wits end. I have installed a reverse camera but I cannot get it to work!!! It is the wired sort with a delay module. The live pig tails on the camera cable are wired to the fuse 19 piggy back and to the green and black wire which I thought was the reverse light?? I have plugged the av cable in to the back of my kenwood head unit via the specific camera lead. Stick it reverse and nothing...... I have no idea where I am going wrong.
