How to Install a Fifth Wheel and Gooseneck Wiring Harness on a 2016 Ford F-250


Today on our 2016 Ford F250, we're going to be taking a look and installing the tow ready fifth wheel and goose neck wiring harness with seven pole, part number 20110. To begin our installation, we're going to have to figure out a spot where we're going to mount our seven way plug. This general area is where we're going to be mounting it. Now I do want to mention before we start drilling or mounting anything, you need to double check to make sure that you have adequate amount of room to get the wires up here as well as there's nothing behind it that we're going to damage once we start drilling. Now I already checked and there's nothing back here and we do have adequate amount of room to get it up. I'm going to mark a hole, mark a spot right there and I'm going to drill a pilot hole to make it a little bit easier when I come back and drill my final hole. Now I'm going to be using a quarter inch drill bit.

Now with our quarter inch pilot hole drilled, I'm going to come back with a two inch hole saw and I'm going to drill a two inch hole right here. Now our first step is to be coming back to our factory seven way. We're going to come back to the back end where the plug is and there's going to be a tab. If you push in on that tab, it'll release the plug. We're going to pull the back of the plug off and we're going to set that aside for right now.

Now we're going to be plugging in our new harness into the back of our seven way coming out of the vehicle and then plugging to teed section back into our plug up here. Now before we do that I want to apply a little bit of dielectric grease to our connections. Just to help with the moisture and keep corrosion down. You can pick this up on our website using part number 11755. Then I'm going to take my factory plug, plug it in, make sure it locks into place. Then I'm going to take the other end of the teed connector and I'm going to come back to my factory seven way plug and plug it in.

Make sure it locks into place. Now the hole we drilled, it's going to be right here on the side just a little bit above our taillight. I'm going to run our wire up around towards the outside and I'm going to come up to our hole. I'm just going to loosely run this wire, reach up, find my hole and I'm going to put it in there just holding it in place for right now. Now here's where our seven way came out. Now I know we just put it in there but we're going to have to push it out to make room so we can put our plug in place.

We're going to mark our four holes and we're going to come back and we're going to drill our 3/32 hole in that location so we can mount our plug. Now reroute our wire back to our hole again. I'm going to go ahead and put a little bit more dielectric grease on this connection. Then I'm going to take our seven way plug that we're going to be installing and I'm going to connect them, want to make sure they lock together. Now I'm going to feed my wire back down and I'm going to put my plug in the mounting location. I'm going to start mounting the four screws that comes supplied in the kit. I'm using a quarter inch nut driver or you can use a quarter inch socket. Now all we have is left is to tidy up our wires in our installation. Now everybody's going to do this a little bit differently, so if you give me a few minutes I'll go ahead and show you how I got mine done. As you can see I ran my wire up but I just coiled up the excess wire and I attached it to the bumper bracket here. As well up underneath the bed and just zip tied everything up. We can still cut our zip ties if we have to make any repairs or move anything but it's not going to get in the way and it's not touching any moving parts or any hot parts. With everything installed, the only thing left to do is to test our seven way and make sure that all of our connections are good and that our lights are working. With an extra set of hands, I'm going to have them come up to the can of the truck and start running my lights for me. Can I have running lights please You can see those are working. Left turn signal That's good. Right turn signal Brakes Brakes and a turn signal The other turn signal The back up lights All right now we know that all of our lights are working and that'll complete our install. That'll finish up our look at the tow ready fifth wheel goose neck wiring harness with seven pole, part number 20110 on our 2016 Ford F250.
