Cutlass Ciera Radio Wiring

I bought a CD player for a spare car I have (Cutlass Ciera International 1989).

The CD player is a JVC KD-S690.

When I took out the old stock radio, there are 3 connectors, 1 power connector and the antenna cable

All I was provided with the new CD player is a cable that has a connector which goes to the radio and a bunch of unterminated wires. (The pinout is included)

How do I go from the connectors hanging from the car to those wires? There aren't any labels or anything on those car cables, not even any labels on the back of the old radio itself. The old radio is a delco.

Are there any harnesses or whatnot I can buy? Adapters?

Thanks

Just to maybe clarify, there are 3 bundles of wires on 1 side of the radio, and another small bundle on the other side near the antenna cable. I also have a retractable antenna so that small cable bundle can be for that?

Any of your audio shops will have the wire harnesses for your car..they plug into your factory connectors and you have to hard wire the other end to the harness that came with the radio..just tell them what car you have.
