How to Install a Trailer Connector Socket on a 2018 Chevrolet Silverado 1500


Speaker 1: Today in our 2018 Chevrolet Silverado 1500, we're going to be taking a look at the Hopkins 7 and 4 pole trailer connector socket with mounting bracket, part number HM40975.So here's what our wiring's going to look like once we have it installed. It is going to give us a seven way RV style connector, so we're going to have all of our lighting functions, 12 volt power, and our trailer brake controller ready for us. And at the same time it is going to give us a 4 pole flat trailer connector, which is going to give us all of our lighting functions, if our trailer doesn't have brakes.Now this is going to be a direct replacement for the factory plug that comes in the bumper. If your Silverado doesn't have that plug, or if you don't want to mount it there, our kit is going to come with a bracket so we can mount it somewhere else like the bottom of our hitch or the bottom of our bumper. And on the outside, it is going to have a legend letting us know which pin is going to do what, which is going to make testing our lights and all the functions really easy. And you just figure out which pin we need to check and it's also going to be on the 4 pole as well.Our connector's going to have a spring loaded cover so it's going to automatically close when we disconnect.

There's also going to be a gasket on the inside so you can make sure that it's not going to have any kind of corrosion and moisture getting inside or any other kind of debris.So now that we've seen the end result, let's show you how to get it connected. To begin our installation, we going to have to pull out our factory plug that's in our bumper. Now on the backside it's going to be just like our socket here. It's going to have these metal tabs and you're going to want to squeeze in on those tabs so that it'll take the pressure off and we can pull it out.As you can see, our plug has seen better days and it's really not even holding that well inside of there so we can go ahead and pull the plug out, and then the connector here is going to have this little white lock tab on it. We're going want to grab it and pull it away from the plug, and then we're going to push down on the center of that black piece, and we're going to remove it.We're going to take our new plug, line up the square on it, make sure it locks in place, slide that locking tab back in, and we're going to feed our wires back in.

And then all we're going to have to do is push it in until it locks into place.Now we have one more thing to make sure that all of our circuits are working properly, so I'm going take my 4 pole tester and if you need one, you can pick one up using part number I26. And if I lift up the lower flap, we'll have a four pin connector, so I plug it in down there. And then I'll have someone run my lights so I can verify that it's working properly. If I turn my headlights on, we can see the tail light function is working properly. Now with the left turn signal, the right turn signal, and our brakes.Let's go ahead and hook our 7 pole tester and make sure that socket's working properly as well.

So you can see my taillights are working, my left turn, right turn and my brakes. Also at the top you can see that we are getting a 12 volt power source at the back of our seven way.If there was a brake controller in our truck, I'd be able to show you that, but in our application, we don't have one hooked up. So all you have left to do is hook up to our trailer and hit the road.That'll finish up your look at the Hopkins 7 and 4 pole trailer connector socket with mounting bracket, part number HM40975, on our 2018 Chevrolet Silverado 1500.
