Electrical Adapters

CURT towing harness adapters make connecting trailers to vehicles with different wiring systems simple.

A CURT trailer plug adapter fits into the vehicle's existing wiring harness, while a trailer wiring adapter converts a vehicle's wiring system to match that of the trailer. Factory harness electrical adapters connect a vehicle's factory-installed towing package to a trailer. 

Our 2-way electrical adapters connect a two-function trailer to a four-way wiring system, while 4-way adapters are the most common type used to connect most trailers to most vehicles. 6-way adapters are used for more advanced trailers and vehicles with more complex wiring systems. 

CURT wiring adapters for trailers ensure proper connection between the vehicle and trailer electrical systems, allowing the trailer's lights, turn signals, and brake lights to function correctly. It is important to choose an adapter that is compatible with both the vehicle and trailer's wiring systems.
