No Radio Accessory Switched 12v+ Wire

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

This:
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.

Hi, normally there must be wires for +12V constant (radio memory backup), ground, +12V switched (accessory), two pair of wires for left and right front speakers, and other two pairs of wire for rear ones, since each manufacture uses different color codes, make and model is required for the wiring diagram.

Depends on the set up. It will supply 12v power to any accessory connected to it when the radio is turned on. By accessory, I mean : powered amplifiers with relays, motorized antennas, additional audio components. Most likely it is to power an external amplifier or sub woofer.

Alldatadiy.com should have the wiring diagram.

Hi, your factory Sunfire wire colors are pasted below. The yellow wire should be accessory. This should connect to the stereo's red power wire. The orange "always hot" wire should connect to the stereo yellow wire--this is only used to keep your station presets in memory. Please let me know if you have more questions, and thanks for using FixYa.

Yes. They are both a wire that only has power with the key in the run or accessory positions.

New Yorker and Fifth Ave have different colors for RR speaker neg. Does either of these match up?

Did the radio play after you took the key out?
And do the chimes come through the speakers?
If so, then you need to get a harness to go inbetween the radio and the car harness.
