Buy a test light at your local parts store ( they are usually about $5.00 ) with the key out of the ignition and all the lights off test each wire, when the light comes on this wire will be your constant power supply, mark this wire. Now put your key in the ignition and turn on the power, retest the remaining wires, when the light comes on this will be the ignition wire.

2008 cobalt accessory wire color for car radio install?

I looked that up as I was puzzled myself, and here is what I found:

Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. Run a wire to the fuse box for switched power.

Or this:
Car Radio Accessory Switched 12v+ Wire: Run a primary wire from the back of your radio to your to the steering column and use the brown wire in the ignition switch harness.

Why are there three dark green radio wires in the 2002 gmc sonoma

According to autozone online, there are two black wires for ground, a dark green to key power, orange to batt power, gray to dash lights, dark blue and dark green to steering wheel controls when equipped, a purple-while for light dimmer and gray to computer data link.
The dark green that has voltage powers the radio and the orange is for the station memory. The gray wire with power when the dash lights are on is for the radio light.

My daughter has a 98 olds 88 i removed the stock stereo and put in a pioneer cd player but i didnt see any wire on the stereo side for the elec. antenna i was wondering how i can wire it to work

Most aftermarket pioneer cd/radio decks have the electrical connector for the antenna that I've seen.

Is this a cd only deck, or does it have radio functions?

Did you use a new harness wiring adapter to get the pioneer radio to work with the old harness?
There should be a color coded set of wires for the power antenna on that. And, then the Pioneer radio should have wires that were labeled for the power antenna.

2003 grand am radio light out however radio works fine what is problem

Most likely their is a loose connection in the radio harness. One of the wires in this harness sends power to the back light on the radio. It has become loose or disconnected. Assuming no other lights are out and nobody has been cutting wires to install an aftermarket radio. If other lights are not working then check your fuses.

I bought the Haynes Repair Manual for the Buick/Olds/Pontiac Full Size (FWD) and it has the diagrams you are looking for in the back of the book. If you have access to an Auto Zone, they have it or try on-line. I hope this helps, good luck

You have connected your harness wrongly..don't always call by the color code. I'd recommend getting in touch with a local mechanic..
