I bought one of those wiring harnesses for pontiacs when i put my cd player in my ta, but the speakers are not working right. I have it all hooked up right (as far as i can tell), but the rear passenger area speakers do not work. the rear trunk speakers work and the front one's work too, but nothing for the other two.

it just dawned on me, i might remember the problem, when i installed it, there was another plug in the radio, does that have those speaker wires in it?
