Recommended Brake Controller And Plug-In Harness For 2021 Suburban Z71 With Tow Package

Updated 08/26/2024 | Published 04/28/2021

Question:

Hi I’m looking for a break controller as well. The vehicle has a tow package but no controller. What good is that? I have a small 3500 pound single axel trailer with electronic breaks. What is the best/ easiest setup? Thank you.

For your 2021 Chevy Suburban, I recommend going with the Tekonsha Prodigy P2 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90885. This is an easy to use controller that works very well with trailers that have electric brakes like yours. I use this exact one on my vehicle and I love it. You will also need Tekonsha Plug-In Adapter # 3016 which allows you to connect the brake controller to your factory tow package plug. I attached some demonstration videos to help.

I could not find the videos of the install of the brake controller on the 2021 Chevy suburban. Can you please send to my email if still available?

@GaryQ I attached the best video I could find for a suburban brake controller install. Unfortunately we don't have a video on your exact year of Suburban, but this should help get you in the right direction. If you have the tow package then you can use a plug-and-play connector as mentioned above and it'll be under the dash as seen in this video. If you don't have tow package, you'll need to hardwire as seen in the attached installation video.
