02 dodge install problem

I've been searching for a solution to my problem for hours and stumbled onto this website so I'm hoping someone can help me. I have a 2002 Quad and I'm having trouble with installing an aftermarket head unit. I connected all the wires correctly to a wiring harness, and the unit will play the radio just fine. But when I try to listen to a CD, no sound comes out of the speakers. The wiring harness has a brown wire that is not labeled and looking at the pin positions it doesnt match up to a wire on the factory side. However, there is a wire on the factory side that does not have an output wire on the aftermarket harness. Has anyone had or heard of this trouble before? Please help. I connected the new unit to another vehicle, and the cd player worked fine.

Where the harness is blue ( power antenna lead) it should be blue/white ( remote on ) . Put the blue/white where the blue is from the deck and you should be fine.

You da man! Wiring harness blue wire says "power ant" which I had hooked up to head unit. That was the problem. Thanks for the help.
