Thank you so much for this video! I could not figure out why my unit was not working until I watched your video. I was simply matching the color of the wires between the electronic braking unit and the OEM wiring harness. After watching your video, I realized that I am a dumba** and should have read which wires did what for the braking unit and the OEM wiring harness. Now everything is working properly. Thanks again!.
Hey man! Thx for the video. I dont think I would’ve ever found that connector without your tip. Totally makes sense why they put the dummy plug on though to prevent accidental shorts. Nice truck. I think I put the exact same step-boards on mine. I have a 2020 Trailboss & Airstream Caravel this is going in.
Thanks for posting this it was a big help! I was originally looking to see if I could purchase the factory brake controller and install it. But I saw another guy who tried it and he said he was unable to get it programmed so that it would show up in the driver information center. I ended up buying a Red Arc Tow Pro Elite. I was going to purchase a Tekonsha harness to plug from the controller harness into that connector under the dash that has the dummy plug in it. After watching this I went out to my 2021 Silverado and opened the glove box. The harness you mentioned was sitting there under the manual. I'm really handy and tackle all of my home repairs and construction projects. But working on a vehicle wiring made a nervous. The section in your video on matching up the different color wires on the 2 harnesses was a great heads up on making sure everything was correct. I installed and wired it today. Thanks again.
Great video! Ive got a 2020 Custom as well and was pretty disappointed that it didn’t come from the factory with a brake controller. Thanks for the great info!
I have a 2021 Silverado with 800 miles on it. I pulled my camper down to get the hitch adjusted and a cap on the back. I knew that there is a "Tow/Haul Mode" knob/switch on the upper left of the dash, and there was a 7-pin connector for the trailer connection. Dumb old me, I figured the computer figured the trailer weight and applied the trailer brakes appropriately since it's all computerized. But NO. There was NO trailer brakes working, even though one of the seven pins is labeled trailer brakes. I wrote a nasty email to my salesman about it. They should NEVER make a truck with a 7-pin connection that doesn't work the trailer brakes! That's very dangerous! I may end up doing what you did. As a matter of fact, I'm going to walk out to the truck now and see if the wiring harness was included. If not, that will be another nasty email to my salesman. You made it seem very simple. Thanks for posting your video. Greg in TN :)
good point, maybe class action suit against GM for providing something that assumed worked from factory ? If assumed had a connector for trariler and indicated the pin for brakes then one could assume was working ? tow and brakes not work and crash, lawsuit.
So i guess it was a fuse and it took them 5 days to tell me that. I don't believe that but all is well. Thanks for the video because with out it i would of never knew the wire was in truck and its a plug and play. They try to say that when the upshift was put in, it blow it but i tried it 1st with out the upshift and did your method
Well, I went out there and damn the factory wiring WAS in the big glove compartment! Now all I have to do is get a controller and harness like you did. Can you update us on how it did? Are there better controllers are is the one you got doing ok? Pluses and minuses? Thanks!
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.
I have the same truck that came with the brake controller already installed but does nothing. You can’t even adjust the gains for the brakes. Did your truck come with a controller already installed and u added an aftermarket one?
Hey Ben! Unfortunately mine didn’t come with one but a friend of mines did and we compared ours. His was having the same issue you are. May be a factory problem. This new one I installed works so good. I just got back from taking my RV from Texas to FL and it saved me a couple times in New Orleans traffic and Houston traffic. Worth having!
@@findaway8030 thanks we are buying a travel trailer and I needed one. That controller is on sale for $39 on Amazon. Not going to get wire harness thanks to your video I doubt I need one.
@@findaway8030 thanks for the reply, i went to the dealer and told them i wanted to see in the truck that I'm picking up Friday to make sure it had that wire oyu showed us, its there with other wires like plow stuff because it has plow package. The plug is in the same spot as yours. Cant wait to pick it up. Thanks again!!
Did not work on my 2021 Chevy 2500 WT. No power coming off the harness from truck. I'm so pissed, i told the salesman that i would of payed $200 more for a truck with it and he was, no you can put one your self. WTF. Going to dealership tomorrow morning and see what's going on, why i don't have power from harness.
@jorge197, my buddy got a 2500 and it worked for him. Can you see if the wiring diagram that came with your harness is different from the one I posted in the video?
@@findaway8030 It's the same as yours. It's at the dealer now and hope they have it done by tomorrow. I think they did not run a power to the harness because there is no power running to the harness but everything else works. I hard wired it so i can have power on box and hooked it up to my travel trailer and everything worked well. They need to fix this, i did not drop 45,000 on a truck that i cant do shit with!!!
@@jorge197 Why I bought a used early 2000 model for my farm this new shit is crap from GM never will not buy any of new crap out now. I can take a good decent shape older model and still put less in with new Eng, trans, and reupholstered interior and paint!
Thank you for the video. Most easiest instructed video I've seen.

So it does work ok?
Thank you for making this video. With detailed instructions. You saved me a lot of headaches. I can't thank you enough.
Glad I could help!
Thank you for keeping it simple, I can now install a brake controller for my Chevy Silverado 2021

Jim thanks so much for the feedback. I’m glad the video helped you out!
Thank you for posting! We just bought a 2021 Trail Boss and have a travel trailer on order. This video will help us so much!!
Appreciate the video buddy, helped me out a lot! Just bought a camper and was freaking out about the trailer brakes. This video eased my mind a lot!
Worked like a charm. Installed the brake controller on my 2020 Chev Crew Cab yesterday! Thanks!
Thanks so much for your video. I like that you didn't assume everyone is a mechanic
Thanks for posting this! Showing the location of the connector in the truck made this super easy, appreciate the video!!
The harness comes with the truck it's in your glove box
Thanks for doing this. It was a huge help.
Excellent, thank you!

Genius. Thank you
Thanks for making this video! How do you like this controller after 2 years of use? Did it work to your expectations?
It’s been working great and has exceeded my expectations. I’ve had 3 other RVs since then and I’ve had 0 issues with it.
Great detail to this video thank you.
Basically basically basically why mess with all the wiring when you can buy the harness plug and play?
Well, I went out there and damn the factory wiring WAS in the big glove compartment! Now all I have to do is get a controller and harness like you did. Can you update us on how it did? Are there better controllers are is the one you got doing ok? Pluses and minuses? Thanks!
Thanks for video. Just out of curiosity does your truck have the 2.7? If so what do you tow and how is that engine for towing/mileage? Thanks!
I get about 11-12MPG and my rig is 6800lbs. It’s the 4.3V6 .
I did add a cold air intake from K&N.
How to configure the controller?
Great! Thanks!
Should this work on a 2020 Silverado LT?
Yes sir!
Does the truck work the trailer brakes at all without this module?
It does not.
thank you..

He’s my dad
I love you too!
Not 2017 chevy silverado?
It should be very similar.
How did the controller work after you installed it. Did you have to get the truck flashed at the dealership?
Hi Roy,
Flashing was not required. It’s worked great so far! I’ve towed my camper about 7000 miles now with 0 issues.
@@findaway8030 thanks we are buying a travel trailer and I needed one. That controller is on sale for $39 on Amazon. Not going to get wire harness thanks to your video I doubt I need one.
Maybe you can do a new video showing how it does thanks.
I really want the OEM controller. Does anyone have the information on how to actually get that done?
Will this work for my 2021 chevrolet silverado 2500hd wt? Thanks for the uplade!!
Hi Jorge, yes it should! Is the harness in your glovebox?
@@findaway8030 thanks for the reply, i went to the dealer and told them i wanted to see in the truck that I'm picking up Friday to make sure it had that wire oyu showed us, its there with other wires like plow stuff because it has plow package.

No problem! Hope your subscribed! Posting a cold air intake video next!
Where did you bought your trailer break control?
Hey Edgar! I purchased it at O’reilly Auto parts!
Is that still the 4” lift and 35’s?
That was 6” lift
heck yea !! thanks dude ! GM and their stupid brake controller !
What size motor is your truck?
It was the V6!
Thank you!
@Findaway How did it work?
Hello?
Greg, it’s been working great! My 7000 pound RV can stop on a dime!
@@findaway8030 great. I just pulled a trailer from TN to WA and it did great. I couldn't have done it without you! Thanks! :)
