Easy-Pull Ring Handle Is Easy to Grip and Pull

Standard 4-way flat plugs have a small surface area to grip when you are pulling them apart, forcing you to wriggle the plugs back and forth to loosen them. You might even pull on the wires, leading to broken terminals or ripped wiring. With the Easy-Pull harness, the plug has a large grip ring designed to make disconnecting a snap. Simply slide your finger into the ring and pull the plug away from the opposite plug to disconnect.

The Easy-Pull is also available as a trailer-end 4-way flat plug. Combine the Easy-Pull vehicle-end plug and trailer-end plug for the easiest possible disconnection. With ring handles on both connectors, disconnecting is as simple as gripping the rings and pulling straight apart. No wriggling, no broken terminals, and no damaged wires.

Built-In LEDs Light Up to Confirm Power

Easily troubleshoot any trailer wiring problems with this lighted 4-way connector. It has built-in LED lights that help you determine quickly and easily if the trailer connector is receiving power from your tow vehicle. Just plug the connector into the 4-way flat on your trailer. No separate circuit testers are needed.

Activate each function on your vehicle and a red light will come on if power for that function is being sent by the vehicle-end connector to the trailer-end connector. If the connection is receiving power for all of the functions, but your trailer's lights are still not working, then you know that the problem is on the trailer end and you will need to check your trailer's wiring. Each function, except for ground, is represented by a separate light, and the functions are labeled for easy identification.

4-Way Trailer Connector Installation

Because the color/function of the new connector wires may not match the color/function of your vehicle wires, be sure to use a tester (sold separately) to determine the function of each wire on your vehicle's tail light wiring harness before installing this connector. Once you've determined the matching functions, use quick-splice or butt connectors (sold separately) to connect the corresponding wires.

The number 1 reason trailer wiring comes up faulty is a bad ground, so make sure your ground wire has a solid and clean connection to metal. To make this connection, you'll need a ring terminal and a self-tapping screw (sold separately).

Quick Tip:

We install a lot of wiring harnesses around here, so we thought we'd share a few tips we've picked up over the years.

• Butt connectors - especially heat-shrink ones - provide the most secure, longest-lasting connection, so we'd recommend you grab a few and swap them out for the quick-splices in this kit.
• Use a circuit tester on the plug terminals once the harness is installed to make sure everything's working. There's nothing worse than figuring out that you have a bad ground or a faulty connection right before you're about to hit the road.
• Be sure to put a little bit of dielectric grease on the 4-way plug to protect the terminals from dirt, grime, and corrosion.
