Video Transcript for Hopkins Custom Fit Vehicle Wiring HM42137 Review

Today, we're going to review part number HM42137. This is the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with the 7-Way Plug. Now, this part will provide a 7-way, blade-style connector in your truck bed for hassle-free hookup of 5th wheel or gooseneck trailer. The connector head right here, you can notice its design has a 90-degree angle, so it's designed to fit into tight spaces in your truck-bed side rails. When you do plug this in, we will retain the use of the 7-way connector at the rear of your truck. This right here, this 7-way, RV-style connector is made of a high impact nylon construction. Helps resist corrosion.

Has enhanced weatherproofing with internal seals and corrosion-resistant terminals. Has this durable ABS plastic lid to help keep out dirt and moisture. Has a nice seal or gasket right here in; a foam seal, so when it does close, it keeps out any moisture to the terminals. If you know, this has a very large oversize hinge and it's to allow the lid to open 180 degrees for simple connecting. Now, this harness will install quickly and easily. There is no cutting or splicing required.

Basically, what you would do is the T-connector on this end, you just plug this into your factory wiring. If you go underneath the vehicle at the rear, you'll unplug the connector that's on your 7-way right now, and this will plug into it and then this will plug back into your 7-way. Then, what you'll do is run this 10-foot length of wiring harness from your rear bumper up to your truck bed and then you'll have this 90-degree connector right in the side of your truck bed, and then you want to install this just like that. That will be in the side of your truck bed. Now, it does come with the mounting hardware, the self-tapping screws. Comes with some terminal grease, so when you do your electrical connections, you want to put some terminal grease on those when you put them together to help resist corrosion, and it comes up with some cable ties to take up any slack in any wiring you might need to tie up, but again the harness length is 10 feet.

Now when you do install this, the one thing you do want to make sure there is a white wire coming out of the wire loom. This has an eyelet. On this, you want to do make sure you do connect this to a good, clean ground. Then, the wires that are in the harness itself. The purple, green, the yellow and the brown wires are all 16 gauge. The blue, red, white wires are 12 gauge, and it does come with a nice set of detailed instructions with good pictures to show you how you make your connections.

Basically, once you T this in to your OEM harness underneath the vehicle, run your length of wire up to the side bed rails of your truck bed, and then you'll just install this. When you line it up, then you push it in. Once you push it in far enough, it will lock into place, and then you use your self-tapping screws to install this into the truck bed. That should do it for the review on part number HM42137, the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with the 7-Way Plug. .

Exactly what I needed. The Hopkins Endurance 5th Wheel 90-Degree Harness is truly plug 'n play. Once you decide on the truck bed location for the new 7-pole plug and drill the hole the rest is simply snap together and you're done. The new harness fit perfectly with the factory 7-pin connector and had plenty of length to allow for the new plug to be mounted conveniently in the truck bed wall. No more cable hanging out over the tailgate. 95342


I have used the Hopkins Endurance 90-degree harness monthly over past year since installation. I have also used the factory bumper 7-pole plug as my towing needs required. Both connectors work every time indicating a solid fit and good contact between the factory 7-pin connector and the added Hopkins Endurance connector. Very pleased with both ease of installation and performance.

Wow what a fantastic experience! It first started when I called to verify I was buying the right 5th wheel wiring kit for my 2009 Dodge Ram 2500. Nicky K was the salesperson that helped me out, she took the time to verify my order and she placed the order for me at that point, I chose the two day delivery option and it arrived on time as she promised. The endurance professional grade 5th wheel wiring kit part # 42137 was so easy that it took me only 45 minutes to install from start to finish, and most of that time was Running the wire from the bed location to the back of the truck where the factory 7 pin receiver is located. this kit is truly plug and play!! If I could do this in this amount of time and not have any problems then anyone can do it. I would definitely recommend this company and this product to all my family and friends. 217333

This item worked excellent. Wimpy tie wraps, I used my own. Drilling a 2 1/8 hole in the box a little scary, but it worked fine. 88451


The trailer plug is working fine. Its handier in the box than down on bumper. Thanks again, Randy

High quality and good instructions. The manufacturer provides plenty of cable to put the additional connector virtually anywhere. 216112

Finally got the right part, my bad the first time, and the Hopkins wiring harness was in my 2006 Dodge Ram truck in less than 30 minutes. Most of your time will be spent drilling the hole in the side of the bed. I used a 2" hole saw vice the 2 & 1/8th (already had the 2" and didn't want to run out and buy another hole saw) and had no problems getting the harness through the hole. Hooked up the trailer and everything worked perfectly. There's plenty of harness, maybe too much, for any application in the truck bed. Great product! 81086

by: Adam M08/01/2016

This harness was a breeze to install. Simple unplug and plug back together, cannot be any easier. Harness was plenty long to locate the plugin anywhere you would choose. Factory style connectors worked perfect. Highly recommend this product and would absolutely buy again. Thanks etrailer for your quality products and wealth of application/installation info available!!! 278019

Product was shipped quickly upon ordering, and received in good condition. Extremely easy installation, 10 minutes max, all while baby napped. Nothing more simple than plug and play. I enjoyed not having to splice and butcher my existing vehicle harness. Customer service with this order, and other orders has always been of the upmost. Keep up the good work. 138897

by: Ray10/03/2014

Super easy install. Only needed about half the length of the wiring harness it comes with. Forget looking all over for a 2 1/8" hole saw. A 2" will do the trick. (The trailer video says 1 1/8", but that needs to be corrected). This harness is well worth the money. 154297

by: Sam Liming05/27/2014

The wiring harness for my gooseneck 7 pole hitch on my Dodge is as advertised. The only problem is I looked under my truck it is not wired with a stock connector. I will have to cut and splice it anyway. Not a problem with the product but with my wiring. 132815

Do you have a question about this Custom Fit Vehicle Wiring?

  • Installing 7-Way Trailer Connector in Bed of 2006 Dodge Ram
  • Hopkins offers a T-Connector type set up, part # HM42137 that would plug inline with the existing 7-way on your bumper and provide a 7-way in your truck bed. The wiring harness is 8 feet long, but any existing slack can be taken up and bundled up under the vehicle with zip ties. Using the T-Type connector will allow a 7-way to remain at the rear bumper while adding one to the truck bed, which you would not have if you simply relocated the existing 7-way to the truck bed.

  • 5th Wheel Trailer Hitch and Installation Kit for a 2004 Dodge Ram 1500 Long Bed
  • Slider hitches can slide back towards the tailgate of the truck which allows for more clearance between the trailer and the truck cab when making turns. Short bed trucks pretty much require a slider for most 5th wheel towing applications because the distance between the centerline of the hitch and the back of the truck cab is so short. If you have a long bed truck then you don't have to worry about clearance and you can use a fixed 5th wheel hitch. For your 2004 Dodge Ram 1500 long bed...

  • The 2001 Ram uses different connectors, so you would want to use the Hopkins # HM42137 to install a 7-way connector in your truck bed. To install, you would use a hole saw to drill a 2-1/8 inch hole in the truck bed where you want the connector located. Push the wiring through the hole, and secure the connector to the bed sidewall using the supplied hardware. From under the truck, pull the wiring through to the underside of the truck.

  • Installing 5th Wheel Hitch on 2004 Dodge Ram Using Universal Install Kit from 1989 GMC Truck
  • Can you tell me who manufactured the kit you have? Without that information, it's pretty hard to say. Assuming you used the Reese Universal Fifth Wheel Hitch Install Kit, part # RP30035 to install the hitch in your 1989 GMC, you could reuse your existing bed rails and frame brackets. To install the bracket/rail kit in your 2004 Ram, you'd need another additional bracket, part # RP58023. You'd also need a replacement hardware kit, part # 58164, as the hardware used to connect the brackets...

  • Installing a 7-Way and Brake Controller on a 2006 Dodge Ram
  • If the 4-Way did not come on the truck from the factory, then there probably will not be a brake controller connector under the dash. Even if it is a factory 4-Way, not all of the 2005-2007 Ram trucks that were equipped with a 4-Way from the factory had a brake controller connector. Your truck may not have one. If you have one, it should be under the dash, just to the right of the emergency brake pedal. I have added a link to a help article about installing a brake controller on Dodge...

If your 2006 Dodge Ram 2500 has overload springs, you will need an additional bracket kit, # RP58186. The 5th wheel hitch you referenced is a slider and is for a short bed.

The slider will allow you to move the fifth wheel head to the rear, for maximum clearance between the front of the fifth wheel and the rear of the truck cab during low speed maneuvering.

  • Parts Needed to Flat Tow a 1998 Toyota RAV4 Behind a 2004 Dodge Ram 3500 with a Truck Bed Camper
  • Before flat towing your 1998 Toyota RAV4 you'll want to verify with your owner's manual or with Toyota that it can be flat towed without causing any damage to it. From my research if it has a manual transmission there isn't a problem but the automatic transmission model cannot be flat towed with all 4 wheels on the ground. To tow the RAV4 you'll need a base plate kit, tow bar, wiring to power the lights, a braking system, and likely a high-low adapter. Plus, in your case you may need...

  • Will a HiJacker 5th Wheel Trailer hitch Fit Curt Rails in a 2004 Dodge Ram 3500 Long Bed
  • It looks like your HiJacker 5th wheel hitch has the 4 tabs at the corners of the base that fit in industry standard above the bed rails. On industry standard rails there are 3 sets of mounting holes. The inner set is 10 inches apart on center, the next set out are 20-1/2 inches apart on center, and the outer set is 29 inches apart on center. From front to back the mounting holes are 22 inches apart on center. If the mounting tabs on the hitch are spaced 10, 20-1/2, or 29 inches apart...

  • Recommended Components for Installing the B&W Patriot 5th Wheel Hitch in a 2004 Dodge Ram 2500
  • For your 2004 Dodge Ram 2500, the B&W Patriot 5th Wheel Trailer Hitch, # BWRVK3200, and B&W Custom Base Rails and Installation Kit, # BWRVK2600, work well with an 8 foot bed. The installation kit brackets will install under the bed and mount to existing holes already in your Ram's frame. If you have a 6 foot or less bed on your truck, then it is recommended that a slider 5th wheel hitch be used to gain the correct amount of clearance between the cab of your truck and the front of your...

  • Availability of 10 Inch Extended Fifth Wheel Pin Box
  • The PopUp Hitch RV5 Extender adds 10 inches of extension, although we don't offer that part or anything identical, a Reese Sidewinder will add 22 inches of extension. If you click the provided link, you can see an FAQ article that explains how the Sidewinder works. There's also a listing of available Sidewinder models and which OEM pin boxes they replace. A sliding fifth wheel hitch like the Reese # RP30051 would offer 10 inches of travel, but you wouldn't be able to drive the vehicle...

  • Fifth Wheel Hitch and Accessories for 2009 Dodge Ram Short Bed
  • The Reese 16K, part # RP30051 would be a good choice. The Reese model has the benefit of a head that pivots side to side as well as fore and aft. This can help make hitching and unhitching easier on terrain that is not perfectly level. These hitch recommendations assume that your truck has the 6 foot bed. For your Ram 1500, you would also need the Custom Installation Kit, part # RP50142-58. The brackets on this install kit are specifically designed for your Dodge Ram 1500 and utilize...

  • Trailer Wiring Harness for an In-Bed Camper for a 2002 Dodge Ram 2500
  • Trailer connector # 20135 is meant as a replacement for the factory 7-Way trailer connector on a 2002 Dodge Ram. If your truck did not come with a factory 7-Way then this connector will not work. If it does have a factory 7-Way then I think I have a better option for you since you need the connection to be more at the front of the bed for the camper. You can use a 5th wheel/gooseneck harness and connector, # HM42137. This will plug in line with the factory 7-Way wiring. Normally the...

  • Placing Fifth Wheel Hitch Install Bed Rails in Bed of 2003 Dodge Ram 3500 Long Bed
  • The distance from the rear edge of the truck bed (NOT the tailgate) to the rear edge of the rear bed rail of the Reese # RP50140-58 fifth wheel hitch install kit is 28-1/4 inches. You can find this information on page 4 of the installation instructions, which I've linked for you. If you need a 7-way trailer connector installed in the truck bed, you can do so using part # HM42137. I've also linked you to install videos for the fifth wheel rails and the in-bed 7-way trailer connector.

  • Availability of Dodge Adapter Harness to Move 7-Way from Rear of Truck with Square Connector
  • I believe we have exactly what you are looking for. The Hopkins 7-Way Harness part # HM42137 is a kit that plugs into the square connectors of your truck and allows you to install a second 7-way elsewhere in the truck bed. Typically this is installed up near the wheel well for gooseneck or fifth wheel applications. The harness is a bit longer than you need at 10 feet but would still work well.

  • Is There a Gooseneck/5th Wheel Wiring Harness Available with a Shorter Length of Wire
  • The shortest gooseneck wiring harness we offer is the Draw-Tite 5th Wheel and Gooseneck Wiring Harness with 7-Pole for Dodge with Factory Tow Package # 20111. This wiring harness is 7 feet long and will install behind the factory 7-Way on your 2007 Dodge Ram Pickup. The Hopkins Endurance 5th Wheel and Gooseneck Wiring Harness # HM42137 that you referenced is a great option, however it does not come in a length shorter than 10 feet. Typically the extra wire from the harness is bundled...

  • Recommended Fifth Wheel Install Kits for 2004 Ram 3500 and 2012 Ram 2500
  • For your 2004 Ram 3500 and the 2012 Ram 2500, I would recommend a Custom Fifth Wheel Install Kit from Curt, part # C16420-204. This kit requires no drilling into the vehicle frame, although holes will need to be drilled in the bed for the bolts that connect the bed rails to the frame brackets. The install kit will work with both trucks, regardless of whether they're equipped with overload springs or not. If you need the 7-way installed in the truck bed, I'd recommend the # HM42137 for...

  • 5th Wheel Trailer Hitch and Installation Kit for a 2006 Dodge Ram 2500 Short Bed
  • For your 2006 Dodge Ram 2500 I recommend Curt custom installation kit # C16420-204. With the custom kit there is no drilling required to install the frame brackets of the installation kit so it takes less time for installation. I have linked a video showing an example installation for you. For a Curt 16K slider hitch there are a couple of options. First, Curt has the E16 hitch, # 16516, which is an entry level hitch. It features a slide bar style jaw. This style of jaw is secure but...

  • Are All Components Included the Hi-Rise Gooseneck and 5th Wheel Trailer Hitches
  • Both the Draw-Tite Custom Underbed Installation Kit, # 9460-39-5W, and the Hi-Rise 5th Wheel Trailer Hitch, # 9480-5W, will have all the needed equipment to connect a gooseneck or 5th wheel trailer to your 2000 Dodge Ram truck. However, components like vehicle wiring, brake controller, or safety chains will not be included with these the two hitches. If needed, I recommend the Tekonsha Prodigy P2 Brake Controller, # 90885, with the Brake Controller Wiring Harness, # 3020-P. I also...

  • Recommended Fifth Wheel Hitch and Base Rail Install Kit for 2004 Dodge Ram 2500 Long Bed
  • You'll want to choose a fifth wheel hitch whose weight capacity exceeds the fully loaded weight of your fifth wheel. A 20K capacity hitch like the Reese Titan # RP30867 will provide plenty of capacity in most instances. The hitch uses a dual serrated jaw that will hold the fifth wheel king pin very tightly. This will make for a more comfortable ride, as the king pin won't be rattling around in the hitch jaws. You'll also need an install kit. A universal kit is available, part # RP30035-023,...
