A CURT Electrical Adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket. It easily plugs in your vehicle’s electrical socket and usually requires no additional wiring.
This CURT Electrical Adapter is designed to adapt a 7-way RV blade vehicle socket to fit a 6-way round plug on a trailer with LED lights. It features built-in resistors for vehicles with computers that don’t recognize LED lights and enables them to be compatible with trailers that have them. It also has a simple plug-and-play design and requires no splicing. All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence.
