We also stock Trailer Light Connectors, Power Converters and Wiring Cables to make the trailer lights function efficiently. Wiring Testers are also available to check the towing circuit and ensure good power supply to the trailer lights. They help spot faulty wiring and connection errors to ensure that the trailer lights function smoothly.

JC Whitney stocks 2 to 7-Pole Trailer Light Connector Wiring Kits for Pickups, Campers and Trailers with I, II and III hitches. These Trailer Light Connectors can be used for taillights, headlights, brake lights, backup lights, electric brakes and the auxiliary battery in your trailer. Wiring Kits generally come with a safety latch that prevents accidental pull-away damage. The Connectors have chrome-plated or brass contacts and color-coded wiring for easy installation.

You can get a One-piece Trailer Light T-Connector that hooks up the trailer light wires to your towing vehicle faster and easier than other Connectors. Trailer Wiring Cables are also available that have color-coded insulation and a black vinyl jacket to resist grease, oil, gas and acids.

Trailer Power Converters can be used on I, II, III, IV and V hitches. These Converters allow your trailer to receive power directly from the battery without depending on the towing vehicle. The taillight can show all three - running, stop and turn signals with the help of Power Converters.

Trailer Wiring Tester

Trailer Wiring Testers from JC Whitney can be used to check your vehicle's towing circuit to ensure that it's working properly. These Testers indicate if power from the tow vehicle is reaching your trailer's Tow Plug. They also help detect faulty wiring and incorrect connections. You can go in for a 7-Way and 4-Way Circuit Tester or 4 Pole Connectors with Circuit Testers.

7-Way and 4-Way Circuit Testers make troubleshooting tow vehicles easy. One side of the Tester can be used to test a 7-Way Plug while the other end tests 4-Way Flat Plugs. You just have to plug the Tester into your tow vehicle's towing plug and operate the turn lights, lights and brakes. If the green light on the tester glows, it indicates that the circuit is good.

You can also get 4 Pole Connectors with Circuit Testers at JC Whitney. These Pole Connectors can be plugged into your vehicle's existing 4-Pole Tow Plug. If the LEDs of the Connector light up, it indicates good power supply to the trailer. You will know exactly which circuit is not working properly as there is a plug for each light. This will help make repairs easier and quicker.
