Video Transcript for Hopkins Multi-Tow Trailer Connector Installation - 2021 Chevrolet Colorado

Hey everyone, Shane here with Today, I have a 2021 Chevrolet Colorado, I wanna walk through how to install the Hopkins Multi-Tow Trailer Connector. This is what our connector is gonna look like when it's installed. It's gonna come with the plug and wiring to wire directly to the factory wiring coming from the vehicle. Nice thing about it, it's gonna give you the seven pole plug, as well as your four pole. The nice thing about having a seven and four pole means, we're not gonna have to purchase an extra adapter.

So if we just had a seven pole plug and we we're pulling the trailer if we just had a four pole, we'd have to get an adapter for that plug. Since we have both, we're not gonna have to worry about it 'cause we have them both right here. Another nice thing about it is each lid is gonna have markings on it. It's gonna tell you what function is in what location on the plug. Right turn, running lights, left turn, electric brakes and backup lamps.

The nice thing with the seven pole plug is it's already come with the wires that connect to your factory wires for your electric brakes or backup lamps. So if we pull boat trailer that has electric blocker reverse lockout, it's nice to have that wire connected so that you can back it down in the water without the brakes coming off. Each one of our lids is gonna be spring-loaded, so when we're not using it, it stays closed. Its gonna have a nice extended tab, it makes it easy when opening it. Each one of our lids is gonna have a rubber ring on the inside.

When it's closed, it's gonna seal against this edge, that's gonna keep moisture, dirt, and debris from getting inside on the connections. As far as the installation, it's pretty simple and straightforward, it's gonna come with-- Now that we've gone over some of the features, lets walk you through how to get it installed. To start your installation, we're gonna come over on the driver's side inside the frame rail, and we need to find this bundle of wires. We're gonna follow it to the connector where it's connected to the frame rail, and we're gonna pull it off and give us a little extra room to work. Pop that off, and pull all these down, and you're gonna wanna strip the tape off that's wrapped around the tire or wires to expose the different colors.

Next, what we're gonna do is the end of it has a covering on it. We're gonna do one wire at a time, we're gonna cut that back. We're gonna strip the end, and we're gonna put a butt connector on it. Now your kit comes with butt connectors, but since this is outside the vehicle, I recommend switching them out for heat shrink. You don't have heat shrink butt connectors, you can find them here. You're gonna need two larger ones which are 10 and 12 gauge, and then three smaller ones which your 14 to 16. The only wire that we're not gonna be cutting off the end is this black wire right here. Now we're gonna take our harness, we're gonna strip back the ends of our wires. We're gonna take our green and it's gonna go to green. Take our yellow to yellow. Brown to brown, blue to blue, purple to gray, and red to orange. We'll come back with our heat source and we'll shrink up all of our butt connectors. Next, we need to remove our dummy plug. We're gonna have a clip on each side that we're just gonna push in, and then we'll pop it out. Now we're gonna take our new plug and we're gonna put it right its place. That should just snap in. We're gonna take our terminal grease that comes with our kit, and we're gonna spread it right over the top of all our connections. What this is gonna do is, any moisture happens to get inside of that, this plug, it's gonna help keep the connection from corroding. We're gonna take this, we'll plug it right into the back of our new plug we just put in. We're gonna line up its slots, and we're gonna push it in till it clicks. Last but not least is our ground wire. If you find it someplace on the metal, somewhere on the body or the frame on that sheet, I think this is gonna be the easiest place to go, straight up to the bottom of the bed where this plate is. Now we'll test out our wiring using an alternate power source. Left turn, right turn, brakes, running lights, reverse lights. Once you've tested everything out, you're ready to go. That's gonna do it for look a at and installation on the Hopkins Multi-Tow, seven and four pole connector on our 2021 Chevrolet Colorado..

2019 ChevroletColorado

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!

2022 ChevroletColorado

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.
Aaron S - 02/21/2023


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

2018 ChevroletColorado

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


Completely satisfied with the product and service.


The trailer hitch receiver didn't fit my truck the way it was intended, even though the description stated it would fit, the width of the frame was bigger than the receiver. When reaching out to etrailer their solution was attempt to bend the thick square tubing to accommodate the frame. Its suppose to be a bolt on product. Not a viable solution, considering the distance to cover was over a half inch. Not happy, wouldn't recommend.

2019 Toyota Tacoma

Worked great 2019 toyota tacoma perfect fit. Thank you


not installed yet need to check wires with trailer plug with a test light first.

2020 ChevroletColorado

Arrived in 2 days. Easy to install.


Installing this 7-pin trailer connection cable was one of the easiest DIY projects ever. Excellent instruction and a quality product. Thank you etrailer.

Worked as advertised. No issues installing it when following instructions provided.
Robert - 05/11/2022


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


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.


videos were a lot of help and it was installed just like the videos showed. no problems and works good.... thanks

2020 ChevroletColorado

This is the slickest product I’ve ever seen for wiring a trailer harness. It snapped directly onto my factory bumper and was very easy to wire. etrailer has a video on installing it which is very helpful.

2016 ChevroletColorado

You have the best price on the item I purchased. It takes a lot of patients waiting for USPS


Video says 14ga but Curt says 12 ga wires black positive to battery not marked has some coating fir undercarriage?


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


Fast delivery. Easy to follow directio ns.


bit tough to install by yourself, so far works as intended


I haven't installed this yet, but should work well.


Worked perfect. Simple instructions. Easy to install


Easy installation

Ram 2500

If you ordered the in bed plug wire on your new GMC 2500 this is just what you need to complete the job.

Very good and easy to install. Thanks.

Great product easy to install


Just like the factory plug. Great quality and easy to install. Used the heat shrink butt connectors.

This wire simply needs to be attached to a clean, bare metal surface on the vehicle's frame.

  • Trailer Wiring Connector For 2021 GMC Canyon Elevation Standard
    In order to hook up trailer lights to your 2021 GMC Canyon Elevation, you need a trailer wiring harness. I would go with the Hopkins Multi-Tow 7-Way Blade and 4-Way Flat Trailer Connector # HM11141144. This is an excellent kit that would allow you to use 4-Way or 7-Way trailer plug. It snaps into the factory hole on your bumper and is very easy to install. You will be attaching this harness to the bare wires behind your bumper.

  • 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...

  • 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...

  • 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...

  • 7-Way/4-Way Kit for 2019 Jeep Cherokee Trailhawk Similar to Factory Wiring Setup
    I looked up the factory hitch and wiring kit for your 2019 Jeep Cherokee and the style of connector is the # HM11141144 which you could install on your vehicle but you'd want to use the 4-way kit part # 118779 as an easy way to get the trailer taillight functions first. This is custom fit for your vehicle and you could cut off the 4-way so that you could wire the harness to the 7-way and you'd be set.

  • How Does Prodigy P3 Brake Controller Install in 2019 Chevy Colorado
    While your 2019 Chevy Colorado doesn't have the factory tow package it does have brake controller install wires ran under the dash like what you found. So to install the P3 you'd need the part # 90195 that you referenced as well as the 7-way kit part # HM11141144 and you'd be set. To see how this controller installs check out the install video link I attached to this page as well. I also attached an install video for the 7-way kit on a Colorado like yours as well.

    The Hopkins Multi-Tow 7-Way Blade and 4-Way Flat Trailer Connector # HM11141144 is designed to fit the Chevy Colorado and GMC Canyon. 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.

  • 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...

  • 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...

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.
