here is the diagram i made since there are errors and omittances from the diagram/chart that everyone is referred too.
fyi, i referenced the tewd for omitted pins and ground wires. i used this to install my 2002 Subaru WRX indash 6-disc... which works just like stock.
you have TWO illumination wires. a positive and then a ground which routes back thru the dimmer. if you dont hook up both to a factory radio, your illumination will be inverted or inoperational depending on which wire you (incorrectly) choose. you must hook up both for proper dimming/operation.
