Hello I bought a Pioneer DEH-24UB Stereo for a GMC Sierra 1990. I am replacing an older Sony stereo. The problem being that there are no instructions and we are trying to install it tonight. Thank you
Type of Electronic: Other
Disconnected the old radio. Dont know what wires go to what
Not sure of the "older" Sony Model Number, but typically the wire colors will be the same as the Pioneer, unless it is older than 1994
Should be able to :a) follow each wire of the Sony & connect the same color wire from the Pioneeror
b) If the Sony wires are not the same colors & the Sony is connected to Factory wiresI can post the Factory wires
Please if you can post the wires my son and i are at a loss. He is 14 and I am mom.
this is Factory wire colors "IF" the Sony was connected to them
NOTE: there are "duplicate" colors that are used for different components & can cause damage if connected wrongBROWN this color is used for the Rear Speaker & the LightsYELLOW this color is used for Ignition + & Rear SpeakerGRAY this color is used for Speaker & Lights
Constant 12V+ = Orange Switched 12V+ = Yellow Ground = Black Illumination = Gray
Left Front (+) Tan Left Front (-) Gray Right Front (+) Light Green Right Front (-) Dark Green Rear Speakers;
Left Rear (+) Brown Left Rear (-) Yellow Right Rear (+) Dark Blue Right Rear (-) Light Blue
