Installing a Trailer Brake Controller - 2018 Silverado

- Опубликовано: 28 авг 2024
- Installing a Curt Triflex brake controller in my 2018 Chevy Silverado 1500 LT in order to tow a camper. The vehicle is "brake controller ready" meaning a simple adapter harness is all that is required to integrate the trailer brake controller with the truck's electrical system. My research indicates that the process will be the same back to model year 2014 Silverado and 2014 - 2018 GMC Sierra as well. I can't comment on how similar this process will be for other vehicle makes, models, and years however.
The video demonstrates how simple the process is and shows how to access the electrical junction box, which port in which to plug the harness and in which orientation, and how I chose the mounting location for the controller.

Thank you for this video! It was the only one I could find that showed me exactly where the plug was plugged in.
Glad I could help
Great video and it worked perfectly for my 2017 tahoe
THANK-YOU VERY MUCH SIR, YOUR A GENTLEMEN !!
Thanks you saved me 250 dollar install at u-haul
Great to hear!
Thanks for the video. Just ordered through your links as I have the same 2018 truck. Cheers!
Much appreciated and good luck with your installation.
Great video!! It's the same for my 2019 Silverado 1500 LD "Legacy" Custom.
That’s the truck I have I’m always wondering if 2018 stuff is gonna fit my 19 LD properly lol. Thanks for the info 👍🏻
Thanks for the information, I would have been looking for hours lol 👍👍
I had that controller before I hated that it flashed everytime I hit the brakes. Traded it out with a Tekonsha P2.
Thanks you so much
I definitely forgive the shaky video. It’s a big enough pain to get these jobs done without having to hold a camera also!
awesome video thank yoo
No problem. Hopefully it helps you out.
I have a cushion the electric brakes only works with the brake controller?, I dont have a break controller in my truck and the electric brakes in my trailer does not work.
Thanks for your very informative vid , i have to do this today on my Chevy . 2020 though , im sure its probably very similar .Thanks again .
Good luck with your install. Thanks for the comment.
My truck has one which function makes that part because I never touched it
Where did you get your wire harness adapter?
I opened my box and the plug-in spot was already taken. I have a 2018 1500 LT. No brake controller stock or aftermarket. It’s the same wires and plug. Wires run straight down under the carpet. Any thoughts on what this could be?
Sorry, I don't know what it could be. Is it a previously owned truck?
My daddy left me his 2006 chevy I had a friend remove it cause it was sparking now my breaks have slowly but horribly gotten louder and worse than ever, even after a 1700 dollar trip to the local tire/break shop
Thanks for making this video but I was wondering if you can help me out, I got this same set up for my 2018 silverado but for some reason once I was done installing it there's no lights on the unit
I haven't run across that issue. I guess check to be sure the harness is plugged all the way into the port under the dash, and also fully inserted into the cord coming from the unit. Could also be you have a bad adapter cord, or a bad unit overall.
@@thecountrylivingproject3263 Thank you for the advice, I sent the unit back and ordered another one and I'll make sure all the connections are in all the way. Thanks again for the reply 👍🏼
Does curt make custom wiring harnesses?
I.e would I be able to buy this set up for my 99 GMC suburban 2500?
The harnesses made for specific vehicles (what I would refer to as custom harnesses) are for those that are brake-controller-ready, for example the one I used in this video. However, I don't think your year Suburban has the available port to use (not brake-controller-ready), in which case you would need their universal wiring adapter. One end plugs into the controller, the other end doesn't have the clip, just separate wires that need to be spliced into your existing wiring under the dash.
@@thecountrylivingproject3263 My vehicle has one, it's a 2 pin plug in that is located on my relay panel in the same spot as yours but it's a different panel and the place where the harness would plug in says NAT...I used my power probe to verify that its tied into my brake switch circuit (when i push the brake pedal in I get battery voltage and when the brake pedal is not pressed in I lose battery voltage). The problem is i cant find any one that sells the harness that is specific to my year, make, and model. Thanks for the video as well as your input but I think your right about needing to splice into the brake circuit.
What is the weight of your camper that you pull? How does your Silverado handle it ?
The camper is 28 ft. with a dry weight of 5,225 lbs. No problems with the towing at all. My truck has the 4.3 liter V6. Rated towing capacity is 7,600 lbs for the truck but I think if I were to haul something closer to that maximum it might struggle a bit.
@@thecountrylivingproject3263 Thank you for the reply! I have the 5.3 v8, I just didn't want to get something to big and have the truck struggling to pull it at 65mph.
Why not use the oem brake controller?
The truck didn't come with an OEM controller installed, and apparently you can't add an OEM controller afterwards on the Silverado. Not that I don't think it couldn't be done but if so it would for sure require much more time and expense.
How can you tell if the vehicle is controller ready?
Probably best place to check is the owner's manual. If that doesn't help, I'd try Google search.
@@thecountrylivingproject3263 Thank you sir. :)
You would rather buy a new car because of soldering 4 wires??? Wow

Easy and so dangerous and suicidal.
