How to Install a Trailer Wiring Harness on a 2014 Ford F-250


Speaker 2: Today on our 2014 Ford F-250, we're going to take a look at and show you how to install the Bargman nine foot-long fifth wheel and gooseneck 90 degree wiring harness. Part number is 50-97-410. Now here's what our is going to look like installed. As you can see, it's just like a standard seven-pole round plug that you see on the back of the vehicle. Having the plug in the bed of the truck is going to eliminate the need for you to drape your wiring over the back of the truck and plug it in when you've got a gooseneck or fifth wheel. This one happens to be nine foot long, so it gives you good reach.

You can even extend it further up if you had an in-bed camper that you wanted to deal with. Our coverage has been designed to last a long time.You can see it's spring loaded, it has stainless steel hardware in here so we won't have to worry about corrosion, and there's a tab there that's designed to fit behind the tab on the seven pole plug. See, as we bring that in, tugs down behind it, it'll prevent that from being removed until you lift that cover back up. Now to decide where you're going to mount your plug, I like to use it as kind of like a template, just figure out where the best location would be. Of course, on these raised edges is a better area.

That's going to give us more room on the backside. Then once you've decided where you want it, you're ready to drill out your two-inch hole.Now we need to feed both of our plugs through our hole there. This one's a little bit tighter because we have to get it through at the same time we're passing that wire through. You just take your time with it, poke it through. Then we went to direct that downward.

Kind of guide it downward, we'll feed the rest of our wiring in. Now as we're pushing this in, it happens on most of the forging, it doesn't quite make the wall before the backside here makes contact with the bed of the truck. This is where the Bargman fifth wheel kit has a big advantage over the others because it's going to have the spacer provided already, so we can slide this on up and over, and that'll step it out just far enough to where we can get it properly secured. Then we won't have to worry about those wires rubbing on the exterior of the vehicle. Now where we're gonna line up the plug here.

We want to make sure it's square, and we'll use a 5/16 inch bit driver to get our hole started.We're gonna use the provided self tapping screws to do it. Now definitely square this up before you start your second hole. Don't want it to be crooked. Speaker 5: Now we're going to tie into the seven pole plug here. This one's a four pole, and seven pole plug on the back of the truck with that t-harness. We're just going to pull these two bolts out or screws out to get access to it. Use a 10-mm. Then we need to press our tab right here on the top, and then just wiggle it to separate. Now we're going to use some dielectric grease here on the plug. This just helps to keep the moisture out, keeps dirt from getting wet in there and causing corrosion, so this will make sure we don't have any issues with that down the road. If you don't have it at home, the part number is 11755. We've got a bumper support right here. I'm going to take my wiring and go right over the top of that. It'll give us good support and also allow us to zip tie any extra off to it. Now that factory plug we're going to plug into the longer socket here, make sure it clicks, and then make sure you can pull it without it coming apart.And this will be the end that is now going to secure into the back of our factory plug. We're also going to treat that with dielectric grease. Now we're going to plug that in the back of the plug. Again, making sure it clicks in place and we can't separate it. Just resecure that with the two screws that we removed. Kinda bundle our excess here, you can see we've got a good area there to wrap a couple of zip ties around, keep everything nice and secure. We'll have, of course, a little bit of slack on this. We don't want to pull on that and on this. You don't want to pull too much pressure on there. Speaker 2: Now we'll test out the system and make sure everything's working as it should. We'll check our running lights first, left turn signal, right turn signal, check our brakes. We can check our reverse signal, and then we can also check our trailer gain. Now if you have 12-volt power hooked up in the front of your vehicle, you can also test and make sure that that's working properly, and that'll complete our installation of the Bargman fifth wheel gooseneck wiring harness, part number 50-97-410.
