Speaker 1: Today, on our 2018 GMC Sierra 3500, we're gonna be installing a truck bed cargo camera for eight-inch factory monitors. Part number 3460010. This high mounted brake light truck bed camera is gonna aim down towards your gooseneck and fifth wheel hitch in your truck bed. This'll make it easier to hook up your trailer, as well as monitoring it when backing up to make sure there's no issues.It mounts directly behind your center high mounted brake light and it circuits tap right into your factory LCD screen. So you won't even realize that it's not a factory mounted camera.The switch included will allow you to toggle between your factory camera and your new center high mounted camera. This is great, so you can watch the hitch at the back of your vehicle with your factory one, or you can watch your gooseneck or fifth wheel hitch with your new camera.It is a 360 degree adjustable camera.

The camera adjusts inside a ball and socket. You can just rotate the camera around and swivel it inside that socket. And now we'll show you how to get it installed on your Sierra 3500.To start our install, you'll need to remove your third brake light. There's two screws that hold it in that you'll remove with a T15 torque socket. I pull and slide our bezel in between the light and our truck here.

So you'll just need to connect the connector. You just push in on that tab and pull out to disconnect it. And it just snaps right back in.Our wiring from our camera is gonna tuck in place, and we're gonna need to get that wire routed up towards the front of our vehicle behind the glove box to connect into the module. An easy way to get this wire up there would be to use a fish wire. We're using a piece of airline tubing as ours.

And we just routed it from the headliner on our passenger rear door. Above the headliner, we routed it over to our opening here. We'll take our wiring from our camera, use some electrical tape, and tape that to our pull wire.We can then use it to pull the wire over. In order to get our fish wire routed over, we went ahead and pulled our weather stripping back here. And that gave us some access to our headliner.

And to make it a little bit easier, we did take the one bolt out on our panel right here. And we took that out using a seven millimeter socket. That just gives you a little more leeway.We'll now pull our fish wire over and feed all of our wiring over. With our wire routed over, we can now reinstall our third brake lamp assembly. And you'll find that the factory screws that come with your vehicle that you remove here aren't gonna be long enough to get your assembly reinstalled. So you are gonna need to go to your local hardware store and purchase some appropriate screws. Doesn't need to be too much longer, but a little bit. At least a quarter inch, or if you're going metric, I'd get one that's about five millimeters longer.We'll then install our new screws. And with both of these installed, we can move on to our wiring. Now we'll take our wiring. We're gonna begin routing it towards the front. We're just gonna go along the headliner here. Now, once we get up to here, our wiring's not gonna be long enough to go all the way forward. Now, there is an extension wire that comes with it, with an adapter. So we're gonna need to plug those in and get those routed.We're gonna use our pull wire trick again to keep routing that wire forward. Once we get to about here, we're gonna start using our extension. Our extension plugs in, it only plugs in one way. So you don't have to worry about plugging it in incorrectly. And we'll continue routing our wire. We're gonna keep routing it down our A filler into behind our glove box. There's a panel located here. This panel just pulls off. This is where you access your fuses. The little bottom corner down here, you'll see a picture of a fuse. That's where you want to pull it. That panel just comes right off.Then at the other end of our extension, we're gonna poke it through the opening here and route it behind our glove box. We're behind our glove box now. The glove box is very easy to remove. There's gonna be four bolts around the inside once you open it. You just take those out using the same T15 torque socket that you used to take the third brake light assembly out.We'll then pull our wire in behind our glove box. Here, your glove box removed, there's four T15 torque screws you'll need to remove. If you just open up your glove box like that, you'll see four screws like that you'll need to take out. Two at the top, two at the bottom. Then it just simply pulls off.We'll then need t
