Video Transcript for Hopkins Multi-Tow Trailer Connector Installation - 2022 Chevrolet Colorado

Hi there Chevy owners. Today nears 2022 Chevrolet Colorado. We're gonna be taking a look at and showing you how to install Hopkins custom fit vehicle wiring harness. And this is what our harness looks like when it's installed. You can see this is gonna pop right in to the factory location where your factory connector would be. So this is a great option for installing one on a vehicle that doesn't have it cause it'll hook to the blunt cut wires located below.

Or if you happen to damage your connector here while working, maybe something slammed into your factory one. You can also use this harness as a replacement harness to get that fixed on that vehicle as well. It's gonna be exactly like the factory one on top. You'll have your seven way connector. It's gonna be a spring loaded latch on there that has a seal on the inside to keep out dirt, debris, and moisture.

And on bottom we've got a four pole connector so you can hook up to just about any trailer. And this one also is spring loaded with seals as well. We'll begin our insulation here at the back of the vehicle on the driver's side just here on the side of the frame rail. You'll find all of your blunt cut wiring for hooking up your connector here at the back. It is gonna be wrapped in electrical tape.

I went ahead and already pulled that tape off of here and then I went and just kind of pushed all the wires apart so we can make our connections. We're gonna go ahead and start with our power wire. Just get that one out of the way. That's gonna be the orange one. This is gonna be live so you don't want to touch that against any metal surface.

It's not gonna be able to shock you but if you touch this against anything metal after you strip it off, it will make a little spark show for you and you don't want that to happen. That's gonna hook to the red wire here on the harness that we've got. So I'm gonna go ahead and have this side strip back and ready. Then we're gonna grab our cutters. You can just strip it back right on the piece here but we don't want all that wire exposed so we're gonna cut some of this off first. I'm gonna basically cut it with just a hair of it left on there, something like this and then we'll use our strippers now to strip that back. And be careful too with your strippers. These are metal too, so if your strippers are touching the wire and they touch something metal you will also have a little light show. So we're gonna come up in here now and strip this back. Now that's our live wire. So now we're gonna think about connector and this actually isn't the ones that come in your kit. You can just get regular butt connectors in your kit and I would recommend not using any of those because they will not seal up. So moisture's gonna be able to get down on 'em which can cause corrosion and can lead to premature failure. So if you want a long lasting connection here on your connector without that's not gonna give you issues down the road. I'd recommend upgrading to these heat shrink butt connectors. We do sell these here at etrailer so you can get those to seal up your wiring. We're gonna slide our butt connector on and crimp it onto the wire. We can then grab our other end here. We already stripped back the red cause that is gonna be the power wire for our connector side. So we'll get our crimpers in place there slide our red wire in and then make our connection. All right, so we've got that one connected. At this point we're gonna do the same thing for each of our wires and making sure that we hook up each one to the correct circuit there. So I'm gonna go ahead and get 'em all connected and then we'll just show you which color from your harness will connect to which color here on the vehicle. All right, so we've made the rest of our connections here. So the first one we did was our orange to red. That's our power circuit. Next, the white wire that comes with the harness here actually has a ring terminal on it for connecting it to ground. We actually just cut that off and I just kind of slid it into the harness and re taped it up and then connected it to the black wire. That's the ground circuit on the vehicle. We've got our brown circuit which is our taillight circuit that just goes brown to brown green which is right turn that just goes green to green. You've got blue, which is your brake controller output that's just blue to blue. And we've got our yellow circuit which is our left turn, that's just yellow to yellow. And last we have our reverse light circuit which is gonna be purple on the new harness to gray on the vehicle. Once we've got all those connections made we're gonna grab our heat gun now and shrink 'em all down. With everything wired over here we can now install our connector. Now there's typically gonna be a just a plastic cover there. Our customer had already removed it. To remove it there are a couple of little prongs just like this on the inside. So you can just give those a squeeze and push that thing out. So now we'll take our new one. You'll want the connector towards the top. That'll just press into place. You'll hear it click in. Before we plug our connector into the back side of it, we're gonna put some dielectric grease on it. That'll just help keep moisture from getting in there and causing corrosion. Just give a nice little thorough coat there. Line up your connector and plug it in. And now at this point we can plug in our tester and make sure everything's working. So we plugged in our tester back there. We just gonna run through all of our lights. I did turn the ignition towards the on position and you can see the clearance lights are already lit up. We'll check our turn signals. There's our left turn, our right turn also hit our brakes. We can see those light up. In the top right corner you'll see that the voltage gauge is showing battery voltage as well. So we can see our auxiliary circuits working. I'm gonna have to start the vehicle to put it in reverse to get the reverse lights to work. And now you should see the reverse lights working there. And lastly, you would check your brake controller output but our customer doesn't have a brake controller installed so we won't have a way to test this. But this one should also be working. The rest of yours are working and the likelihood of that working is also gonna be good. And that completes our installation of Hopkins custom fit vehicle wiring harness on our 2022 Chevrolet Colorado..

Hopkins Multi-Tow 7-Way Blade and 4-Way Flat Trailer Connector - Chevrolet/GMC - HM11141144

Average Customer Rating:  4.8 out of 5 stars   (439 Customer Reviews)

This trailer connector provides multiple towing options for your vehicle without a factory tow package. It includes 7-way, RV-style and 4-way flat sockets, and it connects to your truck's bare factory wiring.

2022 Chevrolet Colorado

I had read that the wires were a little short, but once I got everything connected up they were just fine. It was really easy to install and it looks like the factory installed ones. I did un-tape the harness and cut the ground wire to the length of the other wires then I tucked it in the insulation and taped it all up again before I connected it to the trucks wiring harness.

2019 Chevrolet Colorado

Exactly like the original. Truck came with a empty plug. Easy to wire up and install. You can see it to the left of license plate. Just like factory made.



Still working as it should. Whats not to like about that? Easy to install on my 2019 Colorado WT that didnt come with hitch or trailer wiring. Im 72 yrs. old, so if I can install it. Anyone can!


Works as expected. Used Harbor Freight heat shrink electrical connectors for better install. I think that for the money this kit costs
that it should come with the heat shrink connectors. 2020 Colorado


Perfect fit and proper wiring diagram!


Works great after one year of use. Easy installation if you remember to tie down your rear bumper so it doesn’t fall on your head while working.


Pretty easy to install wished the wires were a little longer (or my truck came with a plug in adapter


No complaints at all

2022 Ford Flex

Looks like it was factory installed. My truck had a wire for the ground so I tucked the white wire inside the flex tubing with the other wires and cut it to the same length as the others. It ended up being a neat looking installation.


I would like to thank the folks at Etrailer for all your help and a great product.
The video on the website made my installation a breeze.
I will use the video on installing the trailer light hook up as well.
Attached is a couple of pictures of the
Curt Trailer Hitch Receiver - Custom Fit - Class III - 2"
Thanks again


Easy to install specially after watching the video.
Works great!


Wired a 7/4 way to 2017 Colorado...
AND easy!!! The colored wiring diagram was accurate.....
The only problem I had was eventually figuring out the Pollak 12-741EV tester you sold me had to be plugged in with the test light indicators facing downwards. A hand held mirror placed under the plugged in 7 way tester did the trick,
and BTW the 7/4 connector only installs one way:
7 pole round on top and 4 pole flat on the bottom.


very easy to install.still as goood as the day i instslled it


Fits loose on the factory opening in my bed. Included wiring harness is very nice/


What we needed to finish a hitch install for a customer.

2023 Chevrolet Colorado

Product as described. Very quick shipp ing.


Great fit, factory look. Wires were short, it was a stretch to get them to the pig tail on the vehicle, I would also have preferred environmental splices, rather than the simple splices provided.


Easy installation and no problems using for this past year.



Absolutely no issues with the connector after another year of use. I can highly recommend this product based on performance and durability.

2023 Chevrolet Silverado 2500

I am over 70 yrs old and have never had delivery service this good my wife and I can not believe the tracking system that you and UPS have developed and use.i ordered a fifth wheel hitch brackets , rails and a electrical 7 way plug. All was scheduled for tuesday and we got everything saturday. I give you 10 stars not 5. George was awesome keeping us up to date. Will recommend etrailer to everyone

2018 Chevrolet Colorado

So super easy to install. Especially when watching your install video beforehand. Great price. Fast shipping.

2019 Chevrolet Colorado

Very easy to install great value. Used my own heat shrink connectors, not the ones supplied with kit.


Fast shipping. The Hopkins wiring harness was easy to install and it looks and fits like an OEM part.


Perfect fit. Just as described.


Product selection, easy navigation, detailed installation videos and exceptional response time will keep me coming back to your store.


Rasy to install

2022 Chevrolet Colorado

Easy to install and fit perfect on my 2022 Chevrolet Colorado.

A year later and everything is still perfect. I use it all the time.

  • Is The 7/4-Pole Trailer Connector Socket Available Without the Mounting Bracket For a 2023 Colorado?
    If you are only needing the 7- and 4-Pole trailer connector socket the Item # HM40975 is the only way we carry it. You will just not use the included mounting bracket. We do have the Kit # HM11141144 if you are adding this connector and also need the wiring for your 2023 Chevrolet Colorado if it did not come with the factory tow package.

  • How To Install a 4-Way Trailer Harness On a 2019 Chevrolet Colorado
    In order to install a 4-way trailer connector on your 2019 Chevrolet Colorado I recommend using the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM11141164 which plugs in behind your taillights and is the only option we have for you that will not require splicing. This harness does come with a powered module that connects to the battery and offers circuit protection for your Colorado but a converter box is not needed as the vehicle already has combined taillight circuits.

  • Are Replacement Installation Clips Available For Hopkins 7-way/4-way Combo HM11141144?
    I have a replacement connector option, but the clips of the Hopkins # HM11141144 you were looking at are not available as a replacement part. Instead you'll need the # HM40975 which has the connector you need with new clips, and is a little cheaper since you don't need another harness.

  • Brake Controller Recommendation and Installation 2019 Chevy Colorado
    A brake controller isn't a vehicle specific item, just about any controller will work on just about any vehicle. There are two types of controllers, a time-delayed and a proportional. A time delayed controller will send the same amount of pre-set voltage to the trailer brakes according to how it's been set. Whether the braking event is a quick tap on the pedal or a panic stop, the controller will send the same amount of voltage to the brakes. A proportional controller will determine...

  • Where Are the Brake Controller Wires On a 2019 GMC Canyon
    The brake controller wires for a brake controller like the Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 on your 2019 GMC Canyon should be located under the driver side kick panel next to the emergency brake pedal. These wires will be taped to one another and most likely tucked under another bundle of wires. If you take a look at the install video on a similar 2017 Chevy Colorado you will be able to see the wires revealed at around the 3:45 mark. Please note if you don't already...

  • Adding 4-Way to 2013 Chevy Silverado that Already has 7-Way Connector and Using Both at Same Time
    For your 2013 Chevy Silverado with 7-Way trailer connector I recommend adding 4-Way # 118384 which will Tee in line with the 7-Way wiring allowing you to have both a function 4-Way and 7-Way connector. Please keep in mind that you can use both at the same time but they are drawing power from the same source. If the amount of power draw is too much it could blow tow package fuses. We used to have an adapter that plugged into a 7-Way and had a 7-Way and 4-Way on the output side but it...

The part you would want to use for your 2022 Chevrolet Silverado 2500 is the 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring # HM40975-11998. This uses the Hopkins 40975 with the Chevy Silverado 2500 end instead of the Hopkins 41144. I have attached an installation on a 2020 Silverado 3500 for your reference.

  • Why Does Crossmember On 2021 Chevrolet Colorado Need To Be Removed To Install Trailer Hitch Receiver
    The reason the crossmember on your 2021 Chevrolet Colorado needs to be removed is it takes up the exact same space as the trailer hitch receiver, in this case the etrailer Trailer Hitch Receiver # e98909 you purchased, and uses the same mounting holes. There would not be a way to use both at the same time. The crossmember is only installed on vehicles without a factory trailer hitch receiver, and with the trailer hitch receiver installed you will have the exact same strength and support...

  • Troubleshooting Right Trailer Light Blinker Not Functioning
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean...

    That is a great question! You can absolutely still use the step on the bumper of your 2016 Chevrolet Colorado once the etrailer Trailer Hitch Receiver # e98909 is installed. The hitch does remove the spare tire support brace that goes directly under the step, but between the bumper mounting hardware and the trailer hitch receiver sitting directly underneath the step that gives you the support the step needs.
