Video Transcript for Tow Ready 5th Wheel/Gooseneck Wiring Harness Installation - 2019 Ford F-250 Super Duty

Hello neighbors, it's Brad here at etrailer. And today we're taking a look, and installing the tow-ready in bed seven way plug that attaches to your factory seven way. So here we have our plug installed and it's pretty nice. It's got a spring-latched lid here. And that's gonna keep the elements out of there. It's also gonna latch onto our seven-way plug when putting in place.

Now having our plug here in the bed, it's gonna be great for when doing a gooseneck or a 5th wheel because you can run your power here and not have to run it off the back of the truck. It's super easy to install. You are gonna have to drill on the side of your bed, which seems a little scary, but really, you should be able to get this done pretty quickly and you're gonna be plugging into factory harnesses, so there's really no splicing involved. It's just plug and play. Now, this is gonna be an ideal setup for when running your gooseneck or 5th wheels, and that way you can plug directly in your bed, without having to run your wires to the outside of the truck.

So to begin our install, we're actually going to be drilling in a hole. I'm using a 2 1/8 inch hole saw and that's gonna allow us to put our plug in place. So right here and then you wanna check the back side to make sure that there's nothing there. Then we'll go ahead and get a little pilot hole and get going on the hole. So now I'm gonna go back on this hole here and just kind of give it the quick filing down to get some of those burrs off then I'm gonna put a little bit of clear coat there just to keep it from corroding long term.

So now, we're gonna take our two plugs, feed them down through the hole. It's gonna be a little tricky. You may have to kind of stagger those wires to where it'll sit properly. But, once through, lightly feed that in that's gonna leave us with this plug. Now we also have our seven way here.

So this is going to attach to it. We're going to get these holes drilled up. So firstly, let's go ahead and clip this together. Okay. And then make sure that this is facing obviously the proper orientation for the plug. Right about there. And now I'm going to run just tiny little pilot holes in here and we'll get that mounted up. So now we're going to go ahead and get this all cleaned up and then we're gonna head under the vehicle to make our connections happen. So now we have our wires running down from the side of our bed. I'm gonna just kind of feed this over and I'll be able to zip tie to kind of kick this clean. Along with that other looming. So just feed it over the frame, it's gonna be quite and easier if you have your spare tire dropped down, as you're gonna have a little bit more room here to work with it. So pretty simple. We find our plug here that goes to our factory seven way. We're going to go ahead and unplug. And then this is gonna just simply, make those connections and jump it into it. So if you're gonna take the other end. Put that in place. And then this is gonna go where our previous plug was. Now, if you can see, the wires are kind of tight here. So I might actually reroute them a little bit cleaner over here, and that way the wires can reach this way. This wire allows me to pull some of that slack through and we can go ahead and get this all zip tied up later. But let's make sure that we have all our plugs in place and everything nice and clean. So now go ahead, make that connection. Snap this into the factory plug here. So now all that's left to do, is get these wires tucked up. I've gone ahead and zip tied up my wires. We had some supplied ones in the kit. But I opted for a little heavier duty ones that we have here at etrailer. They're a little bit longer and make it easier. But, really as long as it's staying up out of the way of the leaf springs or anything catching it on the road, you should be good. So now that we have everything installed, all this left to do is actually test our light functions. So I'm gonna go ahead and start by doing running lights. Next I'll do, my left turn signal, my right turn signal, and then finally my brakes. And that was the look. The tow ready in bed Seven way plug for your vehicle prep with a seven way already..

Mount this 7-pole connector in your truck bed for quick, simple hookup of your 5th-wheel or gooseneck trailer. Custom harness plugs in-line with existing factory wiring. Included aluminum mounting screws avoid galvanic corrosion in your aluminum bed.


Easy to follow instructions for installation. Hooked up and lights worked great.


Couldn't be anymore happier with the way the installation went all the way til the time I purchased them. Customer service Couldn't get any better.


Excellent service. I purchased from etrailer based off of the step by step video that helped with installation!


Everything was handled quickly and efficiently and notifications were available for every step along the way


Easy install. Hardest part was using the hole saw in my aluminum bed. Snapped right in to the existing connector. I also tested out the connections with a meter to insure all were working.


The first harness i ordered did not fit correctly. This harness fit and functioned perfectly. This harness is a very easy install just be sure there isn’t anything behind where you will make your 2” hole. I almost put it where the frame for the bed wouldn’t have allowed it. As always, etrailer was exceptional, even with the harness I had to return! Thanks

Trailer hitch has worked exactly as it should. Could not ask for better performance.


This installation was easy and only took about a half hour to get it done.. It would have take me 15 minutes if I had known that I should notch the hole for the cord to fit through..


Easy to install. Required a 2" hole saw to side of bed.

  • 2019 Ford F-250 Super Duty In-Bed 7-Way Socket Recommendation for Aluminum Truck Bed
    I recommend using the Tow Ready 5th Wheel/Gooseneck Wiring Harness # 20110-010 for your 2019 Ford F-250 Super Duty because it comes with both steel and aluminum screws. Since you have an aluminum bed you'll use the aluminum screws and they won't have any kind of reaction with your truck bed.

  • Troubleshooting 7-Way Connectors On 2013 Ford F-250 Not Working Without Additional Grounding Wire
    It sounds like your Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157 or similar kit may have a damaged ground wire connection. Since this plugs into your factory connectors on your 2013 Ford F-250 the easiest way to determine if the issues is with the additional harness is to remove it from the system. You can connect the factory connection directly to the factory 7-way and test that connection with one of your trailers. If everything works without a jumper you know...

  • How to Adjust B and W Companion Hitch in Truck Bed with Spray In Liner that Fits too Tight
    Sounds like the spray in bed liner has added a bit of height to the truck bed floor and the hitch doesn't want to release now. You can adjust the height of the latch handle which will change the tension. If you check out the picture I attached you can see the section of the install instructions that covers how to do this.

  • Orientation of Pivot Arms to Install B&W BWRVK3300 Companion 5th Wheel Hitch-2020 Ford F250
    Having the scooped corners on your fifth wheel is a neat feature that will eliminate the need for a slider and save you some dollars on the hitch purchase. The 20K capacity # BWRVK3300 B&W Companion you'd looked at would work well for you. As listed in the installation instructions, the hitch head can be installed so that it sits either 3 inches forward or 1 inch forward of the rear truck axle centerline. You'll want to install the arms in the rearward orientation as shown in the diagram...

  • Is An OEM Prep Kit Necessary For A Base Rail Kit To Be Installed
    The OEM prep kit is a puck system, which would be an alternative to a rail kit like the Reese Quick-Install Custom Outboard Installation Kit # RP56017-53 you were looking at. Base Rails and Puck Systems have different attachment point types so you'll need to use a hitch with a compatible attachment type. Most likely your Reese hitch connects to base rails with some pins and clips so you'd be good with installing the # RP56017-53 in your F-250 for the hitch to connect to. If the hitch...

  • Recommended B&W Companion 5th Wheel Hitch-2020 Ford F250 w/ Tow Prep Package
    The exact hitch needed can depend on the weight of your fifth wheel and the length of your truck bed. For a short bed truck, in most cases you'll need a sliding hitch like # BWRVK3370 unless the front corners of your fifth wheel are dished in to allow sharp turns without the fifth wheel corners hitting the corner of the truck cab. A long bed truck would use a stationary hitch like # BWRVK3300. The stationary hitch is also available in a 25K capacity model as # BWRVK3305. For a trailer...
