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 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.

Easy Pull Rings

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.

Average Customer Rating:  4.8 out of 5 stars   (6 Customer Reviews)

Easily disconnect this 4-way flat vehicle-end plug from your trailer connector without damaging the terminals. Large grip ring provides maximum leverage when disconnecting. Universal, 4' long harness splices into your vehicle's wiring.


I had to replace in my Ford F-150 the trailer connector as it failed due due to corrosion. The new 48"replacement was perfect to reach my trailer.The pull harness is the best for trailer lighting I have ever seen.

Very good but I have sold the truck now so I am sure the new owner is getting the benefits of the new harness.
VIRGIL P - 02/03/2022


Holding up well after a year. I like the finger hole, makes unplugging easy.


Always satisfied with you customer service an Products.


Works as advertised!

  • Inner Diameter of Ring on Hopkins Endurance Easy-Pull Harness with 4-Pole Flat Trailer Connector
    The easy-to-pull ring on the Hopkins Endurance Easy-Pull Harness # HM48044 referenced in your question features an inner diameter of 1 inch. The ring's outer diameter is 1-7/8 inches. This is a really nice 4-Way flat trailer connector that has a 4 foot long harness that you can splice into your vehicle's wiring. I have attached a short video demonstration on this product that you can also take a look at.

  • What is the Gauge Size of the Wires in the Hopkins Endurance Easy-Pull Harness # HM48044
    The wire that carries the ground for the Hopkins Endurance Easy-Pull Harness # HM48044 is 16 gauge while the rest of the functions use 18 gauge wire. I have confirmed this with my contact at Hopkins.

  • Matching 4-Way Recommendation to Fit the Hopkins # HM38134
    For the connector that will mate up to the Hopkins # HM38134 that you referenced that has the pull ring and the cover you are interested in you'd want the part # HM48044 for a 48 inch long version.

  • Vehicle Side 4-Way Trailer Connector that is 4 Feet Long
    The Hopkins Endurance Easy-Pull 4-Pole Connector # HM48044 is a 4 foot long vehicle side 4-way trailer connector. It isn't exactly like the Wesbar # W787264 but it is the opposite end and the same length so it will work for you.

  • Screw-Mounted 4-Pole Bracket for Standard Hopkins 4-Pole Trailer Connector HM48145
    Of the 4-pole connector brackets we offer the one closest to your description is the Hopkins Fold-Over Mounting Bracket # HM48595. This works with standard 4-pole plugs like # HM48145 but not with the special easy-grip Endurance wiring such as # HM48044. I checked with Hopkins to confirm.

  • How to Connect 5-Way Connector on Can-Am Spyder RT to 4-Way Connector on Trailer for Towing
    If the 5th pin on the 5-Way of your Spyder RT wiring is for the reverse light function then you can actually plug the 4-Way from your trailer directly into it and you are good to go. However, if the 5-Way has separate turn and brake light functions then what you need to do is cut it off and install the Hopkins Tail Light Converter Kit # HM48895 in its place. The wiring from the Hopkins kit needs to be connected to the following functions: White: ground wire Red: brake light Green: right...

  • Trailer Hitch for 2015 Heartland 2880RLT Sundance 5th Wheel Trailer
    We offer several hitches made specifically for installation on the rear frame of an RV such as your 2015 Heartland 2880RLT Sundance. These are not custom-fit hitches made for any specific trailer but they are adjustable to allow a fit on trailer frames of various widths. All such hitches are shown on the linked page. You will first want to confirm with Heartland (using your trailer's VIN) that it has the capacity to tow the weight of your trailer and cart. Then select among the available...

  • Longest Vehicle End 4-Flat Plug and Lead
    The longest available vehicle-end 4-flat plug and lead like the 48 inch Hopkins # HM48044 you mentioned is a 72 inch (6 foot) plug. There are two of these available, with one that comes with a circuit tester and splices and the other without. - 4-Pole Hardwire Kit with Circuit Tester # 18252 - 4-Pole 72" Long Vehicle End # 18172 For the latter kit - without the circuit tester and splices - you can connect the wiring with the Butt Connectors # 05731-5. I have added links below to video...

  • Availability of Cover for Ford Ranger 4-Way to Protect From Salty Winter Roads
    There are covers for a 4-Way connector to help keep the pins in good shape! I recommend using the Tow Ready # 20112 to help protect the pins on your 4-Way. If the pins are bad enough on the Ford Ranger then you can even cut it off and splice on a new connector like the Hopkins Endurance Easy-Pull Harness # HM48044 (which comes with a cover) with butt connectors # DW05744-5. Adding some dielectric grease like part # 11755 to the connectors occasionally will also help to keep the pins...

  • Bike Rack Recommendation for Magnum Pathfinder T e-Bike on Airstream Trailer Hitch
    The Kuat Piston Pro X Bike Rack # KU98VR can carry bikes with up to a 5" wide tire so it will have no problems with your 3" wide tires. With that being said, we will need to look at a different bike rack for 2 reasons; Kuat doesn't list the Piston Pro X as being safe to use on a travel trailer so if any damage occurs it won't be covered under warranty, and the Pathfinder T has a large rear fender that will get in the way of the wheel holders. For a bike rack that's rated for use on a travel...

  • Trailer Lighting/Wiring Kit for Snowmobile Trailer
    Standard 4-pole trailer wiring uses flat-style connectors, like part # W787268 which is a trailer-side connector and part # HM48044 which is the mating vehicle side connector. On these items and on the 16-gauge bonded 4-pole wire # 16-4B-1 you referenced in your question the usual pin/function assignments are the same. These are as shown in the linked photo and in the article on trailer wiring that is included for you. The one pin that is not like the others will be the GROUND pin which...
