Hey everyone, Shane here with etrailer.com. 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..

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.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.
Sam - 08/24/2022Easy to install and fit perfect on my 2022 Chevrolet Colorado.
Aaron S - 02/21/2023Product selection, easy navigation, detailed installation videos and exceptional response time will keep me coming back to your store.
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.
Worked great 2019 toyota tacoma perfect fit. Thank you
not installed yet need to check wires with trailer plug with a test light first.
Installing this 7-pin trailer connection cable was one of the easiest DIY projects ever. Excellent instruction and a quality product. Thank you etrailer.
Robert - 05/11/2022I 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...
quick 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
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.
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
If you ordered the in bed plug wire on your new GMC 2500 this is just what you need to complete the job.
Thomas - 04/11/2022Great product easy to install
Just like the factory plug. Great quality and easy to install. Used the heat shrink butt connectors.
