Steps
Disconnect the socket harness
Unplug the vehicle connector from the rear of the trailer socket. Release the socket locking tab with a flat screwdriver if it is difficult to turn.
Remove the old socket
Rotate the socket counterclockwise to release its bayonet mount. Push it out through the bumper opening and inspect the connector for corrosion or damaged terminals.
Install the replacement socket
Insert the new socket into the opening at an angle and rotate it clockwise until its lock engages. Apply dielectric grease sparingly to the connector terminals if appropriate, then plug in the harness.
Verify trailer functions
Check that the socket is secure and the connector latch is engaged. Test running lights, brake lights, turn signals, and auxiliary functions with a suitable tester or trailer.
Check your vehicle’s repair manual for exact specifications and fit.
