When you tow different trailers, swapping plugs can get old fast. This connector gives you both a 7-blade and a 4-flat socket in one housing, so you’re ready for just about any trailer hookup. It covers running lights, brake lights, turn signals, reverse lights, and 12-volt power all from one clean mount.
The included harness is set up for everything—lighting, trailer brakes, and charging. Each wire is clearly marked and sized for the job: Red for left turn and stop (14-gauge), White for ground (10-gauge), Blue for electric brakes (12-gauge), Green for right turn and stop (14-gauge), Black for battery power (12-gauge), Brown for running lamps (14-gauge), and Yellow for backup lamps (14-gauge). That makes wiring straightforward and keeps the circuits dependable under load.
The socket mounts neatly to the included metal bracket for a solid, factory-style look. Since it’s a hard-wire design, you can install it anywhere the wiring is accessible. It’s a practical setup when adding towing capability or replacing a damaged connector.
This setup matches what many manufacturers use on new trucks, so it connects securely and holds up to regular use. The spring-loaded covers keep dirt and moisture out, and the combined 7-way and 4-way design makes it easy to switch between trailers without adapters.

This product includes a 7-pole and 4-pole trailer connector socket with a mounting bracket and wiring. When wiring, always connect by circuit function rather than wire color, as color codes may vary by vehicle manufacturer. Use a circuit tester to confirm wire functions before splicing. The white wire with ring terminal is the ground and must be attached securely to clean, bare metal on the vehicle frame.

Steve, the 6 connectors are correct. The ring connector that attaches to the ground wire is the 7th connector.
