Wiring Adapters

Trailer Light Wiring Adapter

Trailer Light Wiring Adapter

Wiring a trailer's brakes and lights can be quick and easy with the right adapter. These trailer wiring adapters speed up attachment and detachment to get you on the road or into the garage faster. Choose from a wide variety of blade and pin adapter configurations to match the wiring style of your vehicle or trailer. Most of the available brake and light adapters use a simple plug-and-play design that allows you to use the existing wiring system of your vehicle or trailer to convert to another type of setup for a new trailer or towing application.

If you usually tow a boat trailer or small utility trailer that uses a 4-wire flat plug but need to switch to a 7-blade plug to accommodate towing your heavier RV-type trailer, you'll find an easy plug conversion adapter for that. The same goes for converting from a 7-blade setup back to a 4-wire flat plug. Northern Tool's selection of trailer wiring brake and light adapters has got you covered. The selection of brake and light adapters doesn't stop at the standard configurations. There's a wide range of other options, too. 6-pin round, 5-wire, and other brake and light adapters are available to match your needs. Need a longer wire? Check out the extensions available to help you bridge the gap between vehicle and trailer. You'll even find some night-glow brake and light adapters that make it easier to check your connections in the dark.
