How to Install a Hopkins Trailer Wiring Harness on a 2019 Chevrolet Colorado

Today on our 2019 Chevrolet Colorado, we're going to be taking a look at and showing you how to install the 7 and 4 Pole trailer connector sockets with mounting bracket and wiring. Now this is what our plug looks like installed. It's really nice because you get a two for one package and what I mean by that, is not only do you have your seven way plug, on the bottom is also your four way plug. Now it even offers that nice factory look. It literally just pops right into place into a factory hole.Now the caps are spring loaded, which means it'll keep on closed when you want them closed, and open when you want them open. On the seven way, you have this retainer clip here to help from your wire from accidentally pulling out.

Now on both sides on the four way tab and the seven way, there is a weatherproof seal, and that'll help keep your connections dry and clean. This is going to give you all your necessary trailer functions. It even has little wiring diagrams on each cap that may help you diagnose any issues you might have in the future.Now that we've gone over some of the features, let's show you how to get it installed. To begin our installation, we're going to remove this dummy plug here. To do that we'll just push in on these silver tabs.

You can do it with your hand or a screwdriver. Once you have them pushed in, it just simply pushes out the other side. We're going to be hooking our harness up to these factory wires, so just to make it a little easier to work with, we're going to go ahead and pull this wiring away and just give us a little more room. Went ahead and cut this electrical tape and pushed it all back. Give me a little more room.

Separate the wires. And now we're going to have to cut all these black heat shrinks off and strip all the wires to prepare them for our new buck connectors.Now with our wires stripped back and exposed, you can go ahead and put some buck connectors on it. Now the kit does come with buck connectors. However, we're going to be using the buck connectors with heat shrink and you can find these on We like to use the heat shrink because this will be outside and just helps keep it a little more protected from the elements.Now we can take our new wiring harness and start to connect it to our buck connectors.

The first wire we'll hook up will be the blue wire from the harness to the factory blue wire. And that'll be for electric trailer brakes if we ever use them. Our next wire we'll hook up will be the white wire coming from our new harness. We will hook that to the factory black wire and that'll be for our ground.Our next wire, we'll take the black wire from our new harness. We will hook that to the factory orange wire and that'll be our 12 volt power source. We will then take our brown wire from our new harness and connect that to the brown wire from our factory harness. You then can take our green from the new harness and put that to the green factory wire. Next is yellow from the new one, and that will actually go to the gray wire coming out of her factory harness. And lastly, our red wire from our new harness that will actually go to our yellow wire from our factory harness.All right, now with everything hooked up, we can use our heat gun to heat up our heat shrink. We went ahead and just wrapped everything up with some electrical tape just to provide a little extra protection. Once you have that done, we can take our end and we'll run it through our hole to the outside. That way we can plug our connector in. Once you have it plugged in, you can come back and zip tie up all this access wire.All right, here's our connector hanging through that hole. Here's our plug. Now the plug does come pre-installed with dielectric grease, however we added some more. It's not a bad idea. But to plug it in, it's pretty straight forward. You simply line these notches up, plug it in. You'll hear it click. And then this white thing is a lock. Push that down. That locks it into place. Once you got that done, we can put it in place. Now the connection side is always going to face up. So your seven way connector will be at the top. This is really easy. You just push it in. You'll hear it clip it into place. That's it.Here we kind of looped up some of our access wire and zip tied it to keep it in place. From there, you just make sure it's plugged in, test it out, and if it works, you're ready to hit the road. And that'll complete our look and installation on the 7 and 4 Pole trailer connector sockets with mounting bracket and wiring on our 2019 Chevrolet Colorado.
