I have two of these rear deck ILB's for the Caprice PPV's. They both have three wires coming out of them, red (12V), black (GRND), and white (Pattern Change). The problem is that when I hook them up, nothing happens. Does anyone know what I'm missing and\or have a manual for them? They were taken from retired cars and worked when removed. I don't know what I'm doing wrong.
Thanks!
Thanks!
