Although there isn't a plug and play wiring harness available for your Cavalier, we do offer a 4-pole wiring harness, part # 18002 which is tapped into the existing taillight circuits. It is a pretty easy process; the wires tap into the existing wiring harnesses behind your vehicle taillights. Luckily, the wire color code for the 18002 and the existing taillight wire colors should be the same. Green would tap into green, yellow into yellow, brown into brown, and the white would be grounded to clean, bare metal on the chassis. Just to confirm, you might want to use a circuit tester like part # PTW2993 to confirm, the wire functions before making the connections.

We have a video of the # 18002 being installed on a 2002 Chevy Impala, click the provided link to view it. The video also shows how to use the quick splice connectors included with the trailer wiring harness.
