How to Install the Curt 5th Wheel/Gooseneck Wiring Harness Installation - 2017 Ford F-250 Super Dut

Clayton: Hello everybody. Clayton here at Today we're going to be working on a 2017 Ford F-250 that we're going to be taking a look at. And I'll show you how to install the Curt in bed 7-Way for aluminum beds. Now there are a few good reasons that you might want an in bed wiring for your truck in particular. And in our customer's case, they have a gooseneck, so it's going to be a whole lot easier to plug up to our trailer with our wiring in the bed.

Another good reason is going to be if you have a fifth wheel. Same reason, you don't want that wire dragging the ground and hanging over your tailgate. So not only is it going to keep our wires safe, it's also going to look a lot nicer when we're going down the road.This is what our 7-Way is going to look like installed. It's just mounted on the side of our bed. One really nice feature is that it has this dust cap here and it's sprung, so you never have to worry about it staying open.

Now there is a really nice seal here on the bottom to keep any dirt or debris out of your connector as well.So not only is our connector going to look really good in the back of our truck, it's also going to function really well. And personally, my favorite part of this kit is it's all plug and play. The hardest part is going to be drilling a hole into our bed. With that being said, I'll go ahead and walk you through how to get it installed.To start our installation, we're going to be working in the bed of our truck. Now our instructions are going to tell us the work underneath first, but I found it a lot easier to do it this way.

So now we'll find a good mounting location for our 7-Way. We found that in the driver's side rear of our bed is going to be a good mounting location, whether you want to do it here or here, you have a couple options. We're just going to try to center it as much as possible. I'm going to grab the center punch and just get our spot marked, that way our drill bit doesn't walk.We now want to grab a small drill bit and drill a pilot hole. Just like that.

You want to make sure not to poke through to the outside. Now we're going to grab a hole saw, we're going to grab the size specified in our instructions, and now drill out the hole in our bed. With our hole drilled out, we can clean up all of our shavings and file this down. Now grab some clear coat and just paint over our fresh cut. That way you don't get any rust or corrosion over time.Now I want to grab our 7-Way and slide it through our hole and try to get it level. That looks pretty good there. Maybe a little bit more. Now you want to grab a small drill bit and just make a mark for our mounting holes. Now we want to take this back off. With our holes marked, we can now drill out those holes. Repeat that same process for our three remaining holes.We can now grab our wiring harness. We're going to push our end with two plugs through the hole, just like so. We just want to drop this down, just like so. When we get to the end of our connector, we just want to plug that in until you hear a click. Give a little tug and make sure it's not going anywhere. We'll drop that down so now we can install our hardware. With all of our hardware tightened down and our mess cleaned up, we can not move underneath and make our connections.Our wiring harness dropped down right here. Now we're going to run it over to our factory 7-Way. In order to unplug our factory wiring, we're going to push in on the tab and then pull out. Now we want to grab some dielectric grease. If you don't have any, you can find some here at And we're just going to add dielectric grease to all of our connections. You want to make sure to use a good amount, just to keep all of our wiring protected.We now want to grab the larger end of our connector and plug that into our factory harness. Push it down then give it a little tug and make sure it's secure. Then we can grab our new plug here. Just kind of flex it a little bit. Then we'll plug that in to our factory connector. There's a little snap. Now we know it's secure and we can clean up the rest of our wiring using zip ties. With our tester box hooked up, we can now go through some of our functions and make sure they're working properly. We'll start with our brakes. We can do our left turn and our right turn and our running lights. With everything tested and wired up, we're ready to hit the road. That's going to do it for our look at and installation of the Curt in bed 7-Way for aluminum beds on our 2017 Ford F-250.
