Trailer Wiring Kits
Custom & Multi-fit


Trailer wiring kits connect to your vehicle at the wiring harness near the taillights, so it is helpful to be familiar with your vehicle wiring before purchasing a trailer wire kit, also known as a trailer wire connector.
Our trailer wiring kits are easy to install and many include plugs, converters, and wires you need to hook up your trailer. Reese, Curt & Valley all carry Trailer Wire Connectors sometimes called Trailer Wire Kits or T-Connectors. So you can always order your wiring kit from the same company you order your hitch from. The styles may vary slightly by brand.
We Always recommend checking with a Custom Trailer Wiring Kit first - as they are the easier style to install. NOTE: Some vehicles will be listed in both sections. It's always better to get the custom kit since they are easier and faster to install and will provide a stronger, more secure connection.
