Re: gauges dont work after new cd player install
You will have to go to the gm garage and ask for the wiring diagram to match the wires up. but the way to fix it the right way is to go to the junk yard and cut the harness out of a car and splice the wires back together then go to wall mart or best buy to get the right wiring adapter then you can match them colors up to your new radios wires and plug into your car

Hello... I will try and help you with your problem. I am assuming that you have cut the factory harness off in the truck? If you have and you can reconnect it, I would recommend doing this and then you can purchase a wire harness adapter and then just match the colors. The benefit in using an adapter harness is the ease of the installation, and the more you change the radio in the truck, the shorter the wires will get. If you do not have the factory harness, or cannot reconnect the old one, here is the hardwire code:
Wire purpose: Truck color: Alpine harness:
6 1/2" Doors
Left Front (+)
Left Front (-)
Right Front (+)
Light Green Gray
Right Front (-)
6 1/2" Rear Corners
Left Rear (+)
Left Rear (-)
Right Rear (+)
Right Rear (-)
what you will need is the radio adapter kit for your car make. also you need a wiring connector for the car between car wiring and radio. match the wires to wires on radio, and then the connector will fit car wiring connector, just plug it in to car wiring.
Check your stereo for a button that says "Aux" or a "Function" button. It could also say something else depending on the radio. The one in my 93' Mustang says "Band" and in my truck it simply says "iPod" Just mess around a little bit and see what you find.
the norm is you will need a volt meter and a 9v battery, test all wires with meter to find a live with the ign switched off, ths is the live memory feed the try again with the ign on, this is the switched live there will be an earth/ground and light feed when you power the lights on. when you do that to find the speakers take a pair of remaining wires and place them on the 9v battery, work through the wires til you here a speeaker crakle, then continue till you find all speaker, that will allow you to hook up to a aftermarket unit, or if you can get to a scrap car of the same year and type, cut the harness out and match up the wires :)
Hook the 12v memory to a constant power, like the cigarette lighter, or parking lights(red I do believe) The yellow one is key powered, so hook that to something that only powers up with the key on. The black one is a ground, that should be obvious. As far as speaker leads, you can take the door panels off and see what wires are connected to the back of the factory speakers. Hope this helps.
Most new radios have wiring accessery kits, or a simple wiring harness kit. the colors match up to your new stereo, and offers a harness that clips into your factory harness. Or, you can look at the diagram to find out which wire is which, and find a wiring diagram for your factory harness and simply line the 2 up, cut off factory harness, and wire them directly.
is it a stock radio? or after market?
if it is an after market radio, you can contact the company that makes it, they normally have an 800 number and tell them you need the manual for that radio... they will mail it to you.
if it is a stock radio you will need to contact the car maker, ask the service dept. cause they will know..
