Easy-Pull Ring Handle Is Easy to Grip and Pull

Easy 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. Some users even pull on the wires. This can lead to broken terminals or ripped wiring. With the Easy-Pull extension loop, 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.


Easy Pull Rings

The Easy-Pull is also available as a vehicle-end 4-way flat plug. Combine the Easy-Pull trailer-end plug on this harness with the vehicle-end plug, and you'll get 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.

Just what I needed. Good quality.

The wiring on one of my trailers was a little tight.
This is a great wiring extender.
The ring is easy to grab especially if hook-up is a bit inconvienent.

One year and product still works like a charm.



by:

The extended terminals with the ring for a grip is especially helpful when using with a newer pickup plug.
With the standard trailer wiring my thumb leaks blood every time I unhook. I purchesed this to cut down on my need for band aids.

  • Trailer Connector Extension to Make it Easier to Plug in Trailer to 2014 GMC Truck
    To make it easier to reach the 4-way connector on your 2014 GMC we have a 4-way trailer connector extension by Hopkins that's 1 foot long, # HM48144, or 2 feet long, # HM47004. Both of them plug into the existing 4-way and just extend it further out from under your truck's bumper. You can leave the extension plugged into the truck and use the included terminal grease to help protect it.

  • Is Wire Size on a 4-Way Large Enough for 12 Volt Power to Charge a Battery
    Basically, yes and no. Given the short distance from the front of the vehicle to the battery the small gauge wire on # HM48144 would more than likely be able to handle the amperage running through it. But the greater the distance the less amperage it can handle. The problem you will run into using 4-Ways is the small wire gauge. As an alternative what about using some winch wiring and connectors, # BDW20306. The connectors aren't much larger than a 4-Way and the wire gauge on these is...

  • Is There a Way To Store 4-Way Inside 2020 Chrysler Pacifica
    Normally the Tekonsha trailer wiring harness part # 118723 is stored outside of the vehicle like you mentioned. In order to store it in the interior of the vehicle you'd need to find a grommet in the truck floor (if present) and route the 4-way through it so that it could stay inside away from the weather. Since this isn't how this was designed to be used/installed there's a chance the harness wouldn't be long enough. If this is the case we have extensions like the part # HM48144 which...

  • What Lengths Are The 4-way Flat Extension Harnesses Available In?
    It sounds like you are looking for a 4-way flat extension harness. I recommend the Hopkins Endurance Easy-Pull 4-Flat Extension 12" # HM48144. 24" # HM47004, or 48" # HM47114. These extensions will plug into the 4-way flat connector on your tow vehicle and the connector on your trailer and have an easy pull finger loop to make disconnecting the harness even easier. If this is not the extension you meant just let me know. I included videos for the products mentioned for you to take a look at.

  • Best 4-Way Wiring for a 2022 Toyota Tacoma Using a Cargo Carrier with Lights and a Small Trailer
    For your 2022 Toyota Tacoma I recommend the Curt T-Connector Vehicle Wiring Harness # C56349. This wiring harness will provide you with the 4-way connector you are needing and has the highest amp capacity. This custom-fit harness connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-Connector, run the hot lead up...

  • Solution For Trailer Wiring Coming Unplugged On Sharp Turns
    The shortest ball mount available for your application is the Curt Towing Starter Kit for 2" Hitches - 2" Ball - 3/4" Rise, 2" Drop # C45534. This is class 3 and rated 7,500lbs max towing capacity. It measures 7-1/2" from center of hitch pin hole to center of ball hole. If this is not short enough, then you will want to just go with a trailer cord extension which is a safer route anyways. If you have a 4 way flat trailer plug then go with Hopkins Endurance Easy-Pull 4-Flat Extension #...

  • Recommended 4-Way Wiring Kit for 2020 Toyota Tacoma and Cargo Carrier/Trailer
    The 4-Way flat connector that I recommend for your 2020 Toyota Tacoma is the Curt T-Connector # C56349. Then, depending on what you have on your Tacoma you might also want to check out the Mounting Bracket # 18144 as well as a no-drill bracket like part # 18140 or # 18136 so you have easy access to the connector. If you don't already have a light kit for your Reese Cargo Carrier # 63153 I recommend the Light Kit # 20174 along with the 12" Extension # HM48144 to ensure that you can connect...
