I recently removed an radio, the iso adapter, speakers and the antenna out of a 93 Chevy Lumina Van in hopes to hook it up in a garage. I figured out what each wire is for and now know the radio do work without the 2 wires for the dimmer and illumination. Is there any way I can hook up the factory illuminating lights within the radio, I mean can I hook up the gray (illuminating) wire to the postive terminal and the brown (dimmer) wire to the negative terminal to get it to work or is their something else to getting the lights to show.

Both the gray and brown wires are 12 volts +. The gray is 12 volts that dims with the dash lights and the brown is the parking light circuit, non-dimming.

Ok so both wires carry a +12v supply to the illuminating lights, but going on what your saying about the grey being the on the circuit that dims the lights and the brown being on the parking lights circuit (non-dimming) would make the gray dimming and the brown illuminating! But just for the sake of having the lights on I could hook up either the brown or the grey to the battery and ground is the black witch is serving the whole unit which I already had connected to the (-) terminal.
Thanks for the advice, greatly appreciated.
