Overview
The Curt Manufacturing 4-way flat wiring connector cover, part number CRT58750, is a protective cover for a 4-way flat trailer wiring connector. It is listed in the Towing category under brake controllers and electrical parts.
Keeping a trailer connector dry
A 4-way flat connector sits at the rear of the trailer where it takes road spray, salt and dirt. Corrosion on the contacts can cause flickering lights or a weak signal, so a cover helps keep the plug clean between uses. The cover is a protective shield and does not replace a working connector.
Inspect the plug and socket for green or white corrosion, bent contacts and cracked housings. Clean the contacts with a suitable contact cleaner and let them dry before connecting. Many people apply a light dielectric grease to the contacts to slow corrosion, and any cover should be checked for cracks and a snug fit each season. Test all lights after reconnecting, with a helper on the brake pedal.
