Today in our 2016 Chevrolet Silverado 2500, we're gonna be installing Mighty Cord fifth wheel/gooseneck trailer wiring harness with seven pole connector. You can get this in a seven foot or 10 foot length. This wiring harness is gonna take your factory seven pole connector that's at the back of your vehicle and reposition it up here, while maintaining the one that's still at the back. What's nice about this is if you have a trailer you haul out of your hitch, you can use the one at the back, but when you hook up your fifth wheel, you've now got easy access to plug your fifth wheel in with the one that's located in your truck bed.The connector itself has a spring loaded lid, make sure it stays shut when not in use to keep out any moisture, ensuring a long lasting connection. On the inside when we open the lid, there's a rubber seal on here to help keep that moisture out even further and our seven pole connector. It comes with all the hardware you need to get it installed, let's show you that now.We'll begin our installation by determining where we want to put our seven way connector.
We're gonna be putting ours in the back where our bed juts out here. So we want to find about the right height that we want it. We're gonna keep it kind of low, we're gonna put it about here. So I like to mark it, so I know where I'm gonna be putting it. And we're just using a paint stick here to make the marks.
This will just give us a general idea of where it's gonna be. We'll now drill our pilot hole in the center with a quarter inch drill bit. Then we're gonna use a two and one eighth inch hole saw. It tells you to use a two inch, but that extra eighth inch really makes it easier to get your wiring in. And you won't notice the extra eighth inch because it'll be covered up with your connector here.If you've got spray in liner like this, I recommend starting with your hole saw going backwards, this will clean off that paint and everything to get down to the metal surface.If you marked it out like I did, then you're gonna wanna clean it off now and get that paint stick off of there.
You can use some soapy water and a rag to get it off. We'll take some clear enamel to spray the hole we just cut. And this'll just help prevent against any rust and corrosion in the future. Now I'm gonna take my wiring, we're gonna take the end that just has the single connector, we're gonna feed it up from the bottom towards our hole. We'll now plug in our seven pole end to the connector.
We can now put our . We'll line it up so it's even and insert our self tapping screws. It doesn't really matter on your first screw if it's not perfectly level, you can level it when you put your second one in. Now I'm gonna adjust that 'til it's level, and insert the other screw. And the rest will go in just the same.We're using a quarter inch socket to tighten all these down. We can now clean up all the metal shavings and mess we made. We'll just vacuum that up. We'll now need to disconnect our electrical connector on our existing seven pole connector. There's a locking tab here that we're gonna need to pry out with our screwdriver. Once you got that out of the way you can press in on the release tab and pull your connector off. We'll now route our wiring up above the frame and over towards our other connector. We can now take dielectric grease, we're gonna squirt it on our connectors. This'll just help keep out any moisture to ensure a long lasting connection and prevent corrosion. We'll take our factory connector that we disconnected from our seven pole connector, we're gonna plug that into the male end of our new harness. You can, if you want, you can put the locking tab back on as well that we had removed. That simply pushes back down on there. We'll now take our other end here, and this is gonna plug back into our seven pole connector.All that's left now is to take your excess wiring, coil it up and zip tie it with the ones included in the kit. Now we'll test it out and make sure everything's working properly. To test it, you'll just want to plug in your fifth wheel into your connector here. Or if you have a tester, you can plug that in. We're gonna be using our tester. And now we'll operate all of our lights and make sure it's working properly. You'll want to make sure you have your left turn signal, right turn signal, tail lamps and brake lamps. With everything working properly, we're ready to hit the road. And that completes our installation of Mighty Cord fifth wheel/gooseneck trailer wiring harness with seven pole connector on our 2016 Chevrolet Silverado 2500.

Mount this 7-way, RV-style connector in your truck bed to simplify hookup of your 5th-wheel or gooseneck trailer. Harness plugs into existing wiring and retains use of factory 7-pole at the bumper.Excellent kit. Easy plug and play. Came with tie wraps and sheet metal screws. Only thing it didn’t come with is the dielectric grease so I suppose if it were necessary they would have included it. Installed on the right side wall of 2018 Nissan Titan XD. Truck has puck system for gooseneck but Nissan didn’t install this in wall until the 2019 trucks which is rather dumb since 2016 with this model and ending with the diesel 2019. 719780

Great product! Good thick wiring covered in convoluted wiring wrap. Easy to install, took longer to brainstorm an area to mount and drill a hole in my new pickup than to actually install the product. Connectors are solid with a easy snap into place design identical to factory pigtails. 609398
