It is not like the the pic fuddy posted above. There'* a sticker on it that says 11/28/95 I'm looking for a pic now

Does it look like this, except has a CD slot?

Yes. That is the tape deck i have sitting around somewhere as well.

That would be a 92/93 cd player then.

Then why does the sticker on it say 11/28/95, why did it come from a 95 grand prix, and why don't my steering wheel buttons work the way they should? The grand prixs must have kept that radio longer. Or the junkyard lied and it didn't come out of a grand prix. At any rate none of this makes sense.

However that explains why my ECC backlighting works.

The cd players are 92/93 and then 94 and up.

They have different harnesses for normal audio hookups, so controls may be the same.

Maybe it was refurbished in 95.

Right. They continued to use that stereo in the Trans Sport and Grand Am.

The point of my picture was to show that a 94-99 Bonneville Stereo can be installed in a 1992 or 1993 Bonneville. That is to be done using the procedure (for jwikoff)

What you have is a stereo out of a different Pontiac. Did you have the steering wheel control wire going to pin No. 6 on the auxillary harness or did it go to a different wire?

You may have a stereo not compatible with your steering wheel controls... But I would try plugging the light green wire into the other pins on the auxillary harness as a check.

If that doesn't work, the other thing you may be able to do is put the correct resistors into the steering wheel controls. But we have to know what those are! We need the wiring diagram from the car you removed the stereo from.

Aha everything becomes clear. wrong radio.

My steering wheel control wire was plugged in to the auxillary harness in pin 6 like you said, and that is what gave me the mismatched controls. There is no way i am skilled enough to remove the resistors that are built into the circuit boards in the buttons, so i'll just live with the mismatched buttons.

Thanks for all the help!

You can just figure out the pin-outs and move them/splice the wires or whatever.
