Dimmer wire
How is this option controlled on aftermarket radio's and do our G-body's have the wire built in to the wiring harness (if so, what colour?). I would like to have this working since the display is too bright and distorted at night on my Alpine deck (you can see the unlit areas). If the wire is not there from the factory will splicing in to the parking lights make it work or is it some kind of other signal that it needs?
Thanks in advance.
