Video Transcript for Mighty Cord 5th Wheel and Gooseneck Wiring Harness Installation - 2023 Chevrolet Silverado 2500
Hey guys, it's Jake here with etrailer. Today we have a 2023 Chevy Silverado 2500. We're gonna be taking a look at and I'm gonna show you how to install the Valterra Mighty Cord gooseneck and fifth wheel wiring kit. Installing the 7-pole in the bed of your truck is, to me, a very important accessory to have in your truck if you plan on towing a fifth wheel or gooseneck. I like having everything that I need to connect the gooseneck or fifth wheel in the bed of the truck. So having a 7-way in the bed of your truck is going to make it that much easier.
Otherwise, people will usually drape your 7-pole over top of your tailgate, which can cause a couple of problems. One being that that cord, every time you make a turn or drive down the highway, is vibrating against the back of your tailgate, which is not good for the cord. You can eventually wear through the insulation on the cord or potentially scratch up or mark up your tailgate. Another thing is if you're plugging into your bumper and you put your tailgate down to unlatch your gooseneck or fifth wheel, you decide to pull away and your trailer's still hooked up, the electric is still hooked up, you could pull up, rip the plug right out of your truck or out of your camper. So having it in the bed of your truck will allow you to connect everything on your fifth wheel or gooseneck that you need to, and then also connect the 7-pole.
You can come around after everything's latched up, plug in your 7-pole, put your tailgate up, and you're ready to roll. Now, when it comes to the insulation, it's going to be extremely easy in our '23 Silverado 2500 because it'll come with a prep kit, which is just a filler plug for an opening that they already have here. And with the help of this Curt adapter, it's gonna look as about as factory as you can get. That being said, let's go ahead and show you how to do it. To begin our installation, we'll take a trim panel tool or a screwdriver.
You're gonna have two tabs on the inside of this plug that we need to remove. Pop it out. Usually if you get one, you can pry on the other. It'll come out. There we go.
One of those rings just fell off. That's okay 'cause we won't be reinstalling this. You might wanna hold onto it if you ever decide to take your wiring back out. But this wiring is literally as easy as sticking these, the pigtail end or the T end of it down through your wheel well. Make sure it comes out which we see there. We'll tie up all our excess length down underneath. We're gonna be using the Curt adapter plate which is designed to cover up the majority of this opening. We'll slide the plug through there. Take our new plug. Snap it in place, make sure it's secured, and then slide our adapter plate over. Tie or plug your opening, and then snap the Curt adapter plate in place. We will secure this using the four self-tappers included in the Curt kit. The Valterra kit will come with some self-tapping screws if you're not using the Curt adapter, but I highly recommend using it 'cause of the clean finish. The Curt screws are gonna be a little bit longer. (drill whirs) With everything secured up here, we'll go underneath and make our connection. Now underneath our truck, we have our spare tire removed just for ease of visibility. We have this white tab here. We'll pop it back, press down on the tab. Sometimes you have to push in on this tab, push in on the plug, and then pull out. So we can take our pigtail here and I'm gonna route it in such a fashion that the wiring is not gonna get in the way of anything. We're up and over this. And typically, in this area right back here is where I like to spool up the excess 'cause there's more than enough space here. You can spool it up right here if you want, but it's just kind of a tight area. Take this. Plug these two connections together. Make sure it clicks, up that tab, and then take our new plug and plug it into the factory. Give it a tug, make sure it doesn't come off. And just like that, you've tied into the 7-pole on the back of your truck by your bumper which will give you full functioning of your 7-pole up in the bed of your truck. All there's left to do is get this wiring all zip tied up. All we have left to do is test out our wiring. We'll hook up our tester box here. That's good. We're already showing 12 volts to the plug. We'll go ahead and run through our functions. We have our left turn, right turn, running lights, and brake lights. With everything working properly, that's gonna do it for a look at and insulation of the Valterra Mighty Cord gooseneck and fifth wheel and bed wiring kit.

Strange that you emailed me. We are actually in Isla morada with our fifth wheel and I was just telling my wife how nice it was to be able to plug the light cord in where it should be instead of draped under the tailgate

Perfect plug and play 5th wheel harness. Shipping is slow and expensive…
by: Robb in Cresson, Texas10/23/2019
Excellent kit. Easy plug and play. Came with tie wraps and sheet metal screws. Only thing it didn’t come with is the dielectric grease so I suppose if it were necessary they would have included it.
Installed on the right side wall of 2018 Nissan Titan XD. Truck has puck system for gooseneck but Nissan didn’t install this in wall until the 2019 trucks which is rather dumb since 2016 with this model and ending with the diesel 2019.

Had to drill 21/8” hole for plug because factory hole was too big
by: Steve01/04/2021
This was a great addition to the tow vehicle. I no longer have the pig tail hanging over the tailgate. I now plug it inside the bed of the truck easy to install and works wonderful

The harness was delivered in great shape and the installation was straight forward. With all hardware within the kit, I didn't have to search in my garage for anything to complete the install. It is as advertised as a plug and play and works as advertised.

Exactly as described, easy to install in the bed of my F350, my 5er can now plug in the bed instead of at the factory 7 pin at the bumper. Excellent product.
by: Cade03/01/2019
Great product! Good thick wiring covered in convoluted wiring wrap. Easy to install, took longer to brainstorm an area to mount and drill a hole in my new pickup than to actually install the product. Connectors are solid with a easy snap into place design identical to factory pigtails.

See what our Experts say about this Mighty Cord Custom Fit Vehicle Wiring
- Trailer Connector Recommendation for 2005 Chevy Silverado Long BedI'd recommend going with the # A10-7010 10 foot long version, as my fear would be that the # A10-7007 might come up a little short in length. I've linked to an installation video for the 7-way and wiring harness that you might find helpful.
view full answer... - Is Modification to a 2001 Ford F-350 Dually Required to Install a B&W Gooseneck Trailer HitchB&W gooseneck trailer hitch # BWGNRK1384 fits Ram trucks but not your 2001 Ford F-350 dually. For your truck you can use # BWGNRK1108. There is no drilling into the frame required to install this hitch but you will need to drill the hole in the truck bed for the gooseneck ball. I have included a link to the installation instructions to the right and a video showing installation for you. You will notice that there is not really any modification needed to install the hitch, even on a dually. To...

Most likely the problem is on the boat trailer wiring connector and is just some corrosion on the pins of the trailer's 7-way. The problem would not be the Mighty Cord. Typically taking some sandpaper to the pins to clean them off fixes the problem. Otherwise you'd want to go over the wiring of the circuit on the trailer looking for any cuts or exposed wire and fix as needed....

To then add one up in the bed you'd want the Mighty Cord # A10-7007 as well and you'd be set with our best budget friendly and easy options.
view full answer... - Recommended 7-Way Splitter for Second 7-Way Connection for Truck CamperWe don't have a 7-way splitter like the photo you sent. We instead for applications just like yours recommend using the Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector - 7' Long # A10-7007 or the 10 foot long # A10-7010. This will allow you have the connection at your bumper as well as a connection in the bed of your truck wherever you choose for a simple connection to your in bed camper. There is no problem with charging your battery for either or both of these connectors....

- Troubleshooting Factory In-Bed 7-Way Gooseneck and 5th Wheel Trailer Connection on 2017 Ram 3500 The in bed wiring harness on your OEM 2017 Ram 3500 connects to the same circuit as your rear bumper 7-way. I recommend removing the T-connector from behind your bumper and inspecting the pins for anything bent. The use some dielectric grease like # 11755 to keep moisture and debris out and reconnect it. Do the same behind the plug in the bed and then test for function. If you don't have the 12V power at that point, then you will want to trace the wire to find the short or replace the...

For your bed rails I recommend the Curt Custom Fifth Wheel Installation Kit # C16444-204. This is a custom fit for your truck and is compatible with or without factory air suspension. These brackets will not require drilling into your frame and will allow you to utilize holes already present. You will still need to drill...

- Correct B&W Custom Installation Kit for a 2019 Chevrolet Silverado 1500The correct B&W Custom Installation Kit for your 2019 Chevrolet Silverado 1500 is indeed part # BWRVK2504 which will work with your Pro Series 16K Slider 5th Wheel Hitch. The B&W Custom Installation Kit does not require any drilling into the frame rail either so this will cut down on install time dramatically. The only other item I would suggest is an in-bed wiring harness, the Mighty Cord 5th Wheel/Gooseneck Wiring Harness part # A10-7007 is a good choice for this.
view full answer... - Replacement Trailer Connector For a 2004 Lance Truck Bed Camper Model 845The 2004 Lance Truck Bed Camper Model 845 most likely uses a 7-way trailer connector because there will be circuits needed for the lights and battery charge line. If you need to replace this then you can use the Epicord 7-Way Molded Trailer Plug with Junction Box part # 277-000141 that you referenced. If you need an in-bed 7-way for your 2011 Chevrolet Silverado to plug this into you can use the Mighty Cord 5th Wheel/Gooseneck Wiring Harness part # A10-7007.

This custom-fit base rail kit will mount using the existing holes in your Ram's frame to drastically reduce installation time and difficulty. If you don't already have an in-bed 7-way then I recommend also picking up the Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector # A10-7007 as...

What you'll need to do is install Industry standard above bed rails (ISR) like # RP56005-53 which are a custom fit for your 2000 Ford F-250 with the 8' bed, and then use a different hitch like the Reese 20k # RP30928.

There are 4 bolts that only get attached to the bed itself when using the Curt Custom Fifth Wheel Bracket Kit # C16448 and rails # C16104 (gloss black) or # C16204 (carbide/matte black). I've attached a video of this installation to assist. You may also want to consider adding a second 7-way like the Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector - 7' Long # A10-7007 which will give you a clean look and easy connection access when towing.

You can use this for towing a gooseneck trailer or you can use the Fixed # BWRVK3500 or Sliding # BWRVK3400 Companion 5th wheel hitch to tow a 5th wheel trailer.

- Will B&W Companion Slider Work on 2016 Ram 2600 With Large TiresIt is possible with any 5th wheel hitch that tires as large as your means your set up won't be level. But really that depends on your pin box height and if you can adjust it. The B&W Companion slider has a hitch height that can be as low as 17 inches, so you need to weigh that consideration against the height of your pin box. It is likely that you will need to make adjustments to your pin box height or raise your 5th wheel to make sure you tow level. To use the B&W set up on your 2016...

There is no an adapter for your old kit, so you will need a new Turnoverball Hitch, but to help you with the install, I have included instructions as well as a video showing it going in a 2016 Chevy Silverado 2500.

It works great. It took very little time to install and is a great addition to my truck. It is much easier to hook up and the cord is in the bed of the truck. I have unhitched the trailer without unplugging the cord with no damages. GREAT PURCHASE
