Hey guys, i was wondering if anyone could tell me the colors of the wires (when installing a radio) for a 1994 chevy astro, i allready found out the yellow is 12 volt constant but i cant figure out which wire is the switched. i think its orange but every time i try it the radio shuts off after "booting" up please help !

Orange is hot at all times - for clock and preset keeping. Yellow is switched.

Orange is the keep alive memory- hot at all times 30 amp chime fuse- holds time and radio presets with yellow power wire off....

Yellow is the 15 amp accessory hot ( on with key in "Run" and "Accessory")

Brown is the parking lite input- to dim the display with lights on

Black is ground

all others are speakers
