2000 venture radio wiring

does anyone know what wires are for what in a 2000 venture for the radio? i could use a breakdown, i need to know what the acc wire is and the constant wire is and what the dimmer wire is. i think i have the speaker wires figured out, but not tottaly sure yet.

those are the easiest ... the speakers are the hardest ones. You might want to try whatever forum a venture is, they would know the car a lot better than anyone here - unless someone here just happens to own one.
