How to Install a Fifth Wheel and Gooseneck Wiring Harness on a 2016 Ram 2500


Today on our 2016 Ram 2500, we're going to show you how to install the Pollak 5th Wheel or Gooseneck T-connector with 7-Pole Trailer Connector. Part number is PK11893-11932. Now we'll plug in our trailer simulator here and the first thing once we put it all the way in, we want to see this first bottom left-hand side light come on indicating we've got 12 volt power. All right, that works out fine. Let's go ahead and start testing our other functions. We can do our left blinker, should have a nice flashing signal.

Now we'll try the right blinker. Let's turn on our running lights and now brakes. If we hit reverse, we should have our back-up light come on. First think we want to do is get our position located for where we're going to be mounting our plug in the bed of our truck. Typically it's going to be back in this area. Now with this particular application, down low here you're going to have a few interferences, mainly another metal plate that kind of goes around that backside.

Right up in this area, we've got a good opening. We're going to be able to install our plug right in there, just like that. You can kind of turn the plug around to get an idea of where you need to lay your hole at in there. I think about right there is going to be our spot. We'll take our 2 and 1/4 inch hole saw and go ahead and drill that out.

You see we'll be able to get that mounted right there, be a really nice location. We won't have to necessarily worry about things sliding back and forth. Should be protected for us. The plug we want to get to is located right behind our factory 4-way and 7-way plug here. We need to lower that spare tire down, give us a little bit of room to work, and also give you some room to see what's going on. That really should be enough to do what we're doing today.

Just want to get it kind of down and out of the way a little bit. Now here's the plug that we're going to be separating. Yours probably isn't going to have this red wire. This is something that the customer has ran, but you will have this loom that's going to run down around here. Just follow that over. Right up here on this top side is going to be a little push connector. Push that in then we'll just wiggle it to separate, just like that. Now we'll take our Pollak T-connector harness here. We're going to use a little bit of dielectric grease or contact grease. It's part number 11755 if you don't already have some. I'm going to do it on both the factor plug-in and also the T-connector there. Now we'll take the T-connector side and we're going to plug it right into the plug where we just removed the factory plug-in. You want to hear that click and you should be able to pull on it. Now you can see this small grey tab. That's something that's still connected onto the T-connector harness. We'll just press that in. That's going to lock everything together. The factory plug should have one here on the backside but it doesn't. Whenever they did the work or whatever they did here with the wiring, they didn't put it back in place. So be looking for that. Make sure we get a good connection. Then we'll start routing it over toward our hole that we've made in the bed there for our plug. Anytime you use a zip tie, always clean off your tag in there. Make it look a little nicer. We'll just keep routing it over. We'll go right over the frame right here. Right on over this way and then just go right along with the harness that already exists there. Now we'll take our plug and let's position it right through our hole that we drilled there. We can go up and mount it. Now we'll add a little dielectric grease to our plug on the top side here. Plug that in. Push the little keeper tab in. We'll bring it right into position and we can use a couple of self-tapping screws to get it nice and secure. All right. That's nice and solid. We'll head underneath, bundle up our excess wire, and then we'll be able to test it out and make sure everything's working properly. This one, of course keep it higher than our frame rail. Don't want it hanging down. Don't want it to get caught up on anything. With everything working properly, that completes today's installation of the Pollak 5th Wheel T-connector and Gooseneck Trailer Wiring Harness, part number TK11932, on our 2016 Ram 2500.
