SOURCE: I need a color code for a Sony Xplod CDX-GT23W.

Guessing that you don't still have the owners/install manual.

On the back of the head unit there should be a group of unused/unconnected wires (with any luck they will be marked), one or more might be an amp turn-on or power antenna lead, so I suggest (with the unit turned on) testing each wire with a DC voltage tester so as to identify and separate any leads supplying 12+ volts. the remaining group will consist of speaker leads. Trial and error testing will determine the proper L & R rear speaker leads.

Good luck

SOURCE: need a wiring diagram for a sony cdx-gt08 it is

yellow to yellow main power wire
red to red key wire
black to black ground
speaker wires are green purple for rear speakers and white and grey for front speakers solid wire color is power and black lines is ground
orange is dimmer switch you wont need it
blue wire is for power anntenna your car shouldn't have it and blue with white stripe is remote wire if you have an amp it will shut off your amp when hooked up any other wire unnessary for your car some head units need a anntenna adapter to work good luck. remember ground before anything and disconnect the battery so you don't blow the fuse
