installation question

i have a cd player with 2 rear and 2 front speaker plug ins and the antenna (kcd-7009 kenwood), i have a older 92 cavalier and i was told i need an adapater to installl my cd player, can anyone help me out with exactly what i need? right now my radio that i took out is connected with what looks like an 8 prong type thing and then it has the antenna.

You need a wiring harness for your car. Just go to Best Buy or Circuit City and pick one up. It will plug into that plug you have in your car, and then it will have wires that you splice onto the wires that came with your headunit.

is there any place to buy the plugw/ the wires that i would need to splice into the wire harness? i got the cd player free from a CRX which had a kenwood radio player orignally and the cd player doesn't have the plug w/ the wires to splice into the wire harness? can i buy one for it?
