In my 97 SSE, I have the stock AM/FM CD player. On the back are two female connectors. One is on the right side of the radio as you look at the back. It is where the large connector/wire bundle connects. Obviously the power wires, speaker wires and whatnot. Then over to the left center, there is a second 9 pin or so female connector. Connected to it is only one wire. What is that second connector? And what is that one wire operating? And what other items can be connected to that connector?

Thanks for your help.

That orange wire, powers your Bose amplifer. Without power to that..you have no sound.

As for inputs on those wires... IDK

yup, the orange does just what Boostie said.
Otherwise it can be used to use a factory remote cassette player like some 96+ Grand Am'* have, or if you had a AM/FM/Cass instead of the AM/FM/CD you could control a factory 12 disc cd changer by using a wiring harness that plugs into that same outlet.
You could still do either one of the above, but you would have to splice the existing orange wire into the orange wire of the wiring harness for the remote cass/CD units.

Also, if you are putting an aftermarket radio in you will have to splice that orange wire into the main power wire to the radio, but I'm not sure... it could possibly drain the battery as I forget if the power wire to the radio is continuous.

I gave the orange power from the amp turn out output from my aftermarket HU.. works like a charm

So, would something like this work to provide an input for an ipod? http://www.installer.com/item/display_item.php?it=pxgm9

How'* maybe sound?

I don't think anyone has ever tried it.
