How to Install the Hopkins Endurance Fifth Wheel Wiring Harness on a 2015 GMC Sierra 2500


Speaker 1: Today on a 2015 GMC Sierra 2500 you're going to be taking a look at and I'm going to show you how to install the Hopkins endurance fifth wheel gooseneck 90 degree wiring harness with seven pull plug. Part number 41157. It's going to give you your brake lights, your right turn, your left turn, your running lights, your grounds, your reverse lights, and it's also going to give you a wire to hook into the brake controller, which the 2500 normally has a brake controller already installed in the truck. This allows you to run that break controller.It's going to give us the option of plugging in when we have our gooseneck hooked up plugging in our wiring here instead of running the wire over our tailgate and plugging it into our factory setting way, which is normally mounted on the bumper. Your lift is going to be spring loaded, it's going to have a nice foam ring on the inside of it to help seal all of your connections, help keep any dirt, debris, moisture from getting inside of the plug housing. Plug housing is going to be made out of a durable plastic.

It's going to withstand all types of weather. Your lid's also going to have a nice little extra tab here. It's easy to get ahold of when you're ready to use it.Wires all hidden, runs down in between the inside of the bed of the truck and the outside finder of the truck. Runs on right between them, and then it's going to plug directly into your seven fold plug on the truck itself. As far as the installation goes it is very simple.

You have to drill a hole to mount your plug here on the inside of your bed, and then you have four self tapping screws to hold that in place. You run your wire down, connect it into the existing plug on the truck.First thing we need to do is find a mounting location for our seven fold plug. This right here is going to be our stake pocket. And, looking down there I don't know if the channel between the inside and the outside of the truck bed is going to be wide enough for our plug and our wire once it's put together to fit in there. So, I'm thinking we're going to have to go right in here.

What we're going to do, we're going to take 2/8" whole saw, we're going to drill our hole right here. You just want to make sure that we have plenty of room on the other side and we're not going to go to the outside of the bed or hit anything underneath.Now I'm going to take a file and knock off the burs. Then we'll take some clear coat, or if your bed's color you have an insert in it you can use black, whatever. We're just going to take some paint and cover up that bare metal to help reduce and rust or corroding later on down the road. Now I'm going to use a piece of string with a bolt on the end, or a nut on the end of it, just to weight it a little bit.

I'm going to drop it down through the hole, it comes out of the bottom, and I'm going to take the single end of my plug or my wiring onto that nut and pull it back up through the hole. It's going to come with some dial electric grease or terminal grease. We're going to put it on our metal connections there.We're going to take the plug in like that. Push it together until it clicks. Now we're going to take a quarter inch socket and then you're going to have some self tightening screws that come in your kit. You're also going to have a couple of washers. I like to go ahead and put those on. Get one started here. We go ahead and remove the spare tire to make it a little bit easier. We're going to go ahead and route our wiring over to our existing seven fold plug coming in to the back of our vehicle. Go right over the top here. Remember we got our spare tire going to put back into place. And we're going to have about nine foot of extra wire here. Going to go ahead and roll it up.This kit's going to come with some zip ties. I recommend picking up a little bit longer ones. Ones that come with are really small and they're a little hard to work with. Then we have the existing wiring right up here running across the back. Cut off our excess. We're going to have our factory set one here, we're going to pull out on this little white tab. Push in in the center there. Push in in the center, pull our plug out. And then you're going to have a second pack of terminal grease or dial electric grease. Go ahead and up those on our plugs. So now what we're going to do is we're going to take our new plug that's going to plug into our seven fold we already have on on the back of our vehicle, and we're going to take our existing one that we took off and it's going to go into the other end of the new one.Push it in until you hear a click. Push in on the white clip, that will hold it in place. Now I'm going to take a 5/16 socket. Your kits not going to come with a self tapping screw for this ground wire. One place that was suggested to put it on is there's a bolt right here holding this wiring on, there's another one on the back side. Except if it's been on there a while you're probably not going to get it off. I suggest picking one of these up, picking a self tapping screw up, and just mounting this to some metal. You look right here, as a brace it goes right to the bed of the truck. Just like that. I'm going to go ahead and utilize these holes right up here with some extra zip ties just to make sure that my wiring is not going to be let loose down here.Now we'll test out our wiring using an alternate power source. Brakes, left turn, right turn, running lights. That will do it for a look at and installation on a Hopkin's endurance fifth wheel gooseneck 90 degree wiring harness with seven fold plug. Part number 41157 on our 2015 GMC Sierra 2500.
