How to Install a Bargman 5th Wheel/Gooseneck 90-Degree Wiring Harness on a 2017 Ford F-250 Super Du


Ryan: Hey everybody, Ryan here at etrailer. So now on our 2017 Ford F250, we're going to be taking a look at and showing you how to install the Bargman 90 degree, seven-way for fifth wheel and gooseneck trailer hitches. Now this kit is going to be designed for trucks with aluminum beds. Many of the questions we get asked, especially with the aluminum bed Fords, is this kit going to work or potentially damage their truck bed The answer is this kit is going to be specifically designed for aluminum beds, and that's because the screws that actually hold our plug in place are made from aluminum. So we're not going to have to worry about any corrosion issues, or things of that nature as like some of the other plugs that use just your traditional style steel screws. And because of that, the steel screws will eventually corrode and cause a little bit of damage.

With this set up, we're not going to have to worry about that.So the cap on our plug is spring loaded and on the bottom of it, there is a rubber seal. That way when we're not using it, it'll sit nice and tight. We don't have to worry about moisture or anything like that, getting inside potentially damaging our terminals. There is going to be a little catch here, and that's nice because once you plug a plug into the seven-way, that little catch is going to prevent it from getting accidentally pulled out. So all-in-all our connectors ...

It's going to allow you to plug your wiring in right here and not have to worry about draping it over your tailgate, reaching down to your bumper and getting it plugged in that way. With this it will be super easy, super clean and straight forward.Now, as far as the installation goes, the more or less just tees right into the factory wiring, so it isn't all that complicated and shouldn't take you a whole lot of time. Speaking of which, let's go ahead and hook that up together now. To begin our installation, we're going to be working inside of our bed. And on the driver's side, you're going to want to find a spot to actually mount up your plug.

Since our truck has a plastic bed liner, what I think is going to be the easiest is if you utilize this hole, it's in the bed liner that's already there. And then grab a hole saw and carefully drill through. I want to be sure and check that there's nothing on the other side that you could potentially damage. So I verified that, now we can go ahead and create that opening.Now that our hole is made, I'm just going to take some clear spray paint just to get a coating on that bare and exposed metal. Give this a couple of minutes to dry and come back and get our wiring put in place.

We can take the ends of our wiring and one at a time, feed them into the hole. Work that in there, and get a little tight. And you can find that sweet spot and it should drop right in. You get them through, we can just continue to push to drop that wiring to the bottom side of our truck, to get all that slack in.So I went ahead and just kind of peeled my plastic bed liner back just to make it a little easier to see and work with. What we're going to do though is hold our plug nice and level. And I'm going to use a small drill bit and make a pilot hole, put the screw in it, pilot hole, screw in it, and so on. The reason I'm doing these pilot holes, because the screws are aluminum. And so they don't really cut all that well or dig in all that well right off the get-go. So that pilot hole really helped that out.Now that our plug is secured by all four screws, you can go underneath the truck and get it plugged in. This is where our wiring came down. I went ahead and just kind of ran it over our frame rail, right to here where we can plug it into our factory seven-way connector. Now, before we do that, what I like to do is take some dielectric grease and just really coat those terminals to keep them protected from corrosion. Does not come included with this grease, but if you need it, you can find it here at etrailer.So once we have that done, you can just kind of set it aside for now, move up to our factory plug and pull it out. There should be a tab here in the center. If you push down on it and pull back towards you, it will release. What I'll do is just put a little more dielectric grease on this side, it can't hurt. I'm going to take one end of our new wire, plug it into that factory connector, take the other end and plug it into the back of our factory seven-way plug. Now that I have everything plugged in, what I can do is grab some zip ties and secure our wiring to help clean up our install look.So this is what our wiring looks like once it's zip tied and secure. Now, it is always a good idea to test your wiring to make sure it's working properly. In our case, I'm using this tester box, but you could always just plug it into your trailer and do it that way. We'll go ahead and hit our left turn, our right turn, our brake lights, our running lights. Go ahead and hit our brake controller and our reverse lights. And that'll finish up our look at and our installation of the Bargman 90 degree seven-way for fifth wheel and gooseneck trailer hitches for trucks with aluminum beds on our 2017 Ford F250.
