I am looking for a wire harness for a DEH-2300

go to store that sells car decks and look for a wiring harness for ur car its about $7 mybe and prettymuch match the colors on ur deck to the harness and then pull ur old deck out and pull the harness from the back the back of that deck and plug that into the wire harness u just bought and hook up the antenna for radio andput the deck into the dash the wire harness should also come with so directions too just in case

The red wire on DEH-P3600 should have a tag on it that labels it as accessory. When wire harness is plugged into unit and you are looking at it from back the red wire should be on left of yellow wire right next to it with no open space between the two. Hope this helps!

if the wire harness plugs into the back of the deck it should work.

All name brand radios have a standardized color codes coming off the harness.

Yellow- Constant
Black- Ground
Red- Switch power
Blue- Antenna
Blue/white- Amp turn on
White- Left front +
White/black- Left front -
Gray- Right front +
Gray/white- Right front-
Green- Left rear side
Purple- Right rear side.......the black stripes are your negative speaker outputs.

No need to guess what wires go where. Buy a wiring harness for your specific year, make and model.

You make connections from your pioneer harness which are all marked, to the Harness you will purchase for your car. They cost about $20 and can be purchased at most autopart stores, or major electronic retailers.

Once you make the connections from the pioneer harness to the harness specific for your car, simply unplug your factory radio and plug in your newly wired one.

Found the manual on Crutchfield's site

The wiring diagram is on Page 25

Hello clarky909,

On your Alero, the 12V constant wire is ORANGE and should connect to the YELLOW wire coming from the DEH-2300 wiring harness. 12V switched on your Alero is YELLOW and should be connected to RED coming from the DEH-2300.

Hope this helps.
