Will the Tekonsha Prodigy RF Wireless Brake Controller Work w/a Factory 7-Way on a 2022Mercedes GLS?

Question:

Want to purchase the Tekonsha Prodigy RF wireless brake controller. I do have a factory installed tow package with a 7 pin connector. Online it says this fits the 2022 Mercedes GLS WITHOUT factory tow package. Will this work with mine even though I have the factory installed Tow Package or is there a similar one to purchase?

Hey Todd. The Tekonsha Prodigy RF Wireless Brake Controller item # TK94FR will indeed work with the factory 7-Way connector on your 2022 Mercedes GLS. The only issue you may encounter is if your trailer has LED lights. If so you'll also need the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass item # 20142.

The Tekonsha Prodigy RF item # TK94FR is going to plug directly into your factory 7-way. It installs on the tongue of your trailer and has a included remote that allows you to make adjustments from inside your Mercedes.

What kind of trailer are you pulling?

Thank you so much Jerred! We just bought a new 6' x 12' enclosed trailer. It does have LED lights on it so we will add that adapter. Thank you! I have two different vehicles that will be pulling this trailer so thought the wireless controller was the best solution. Would you recommend something different or think this is a good solution?

@ToddA You're welcome! The Tekonsha Prodigy RF Wireless Brake Controller item # TK94FR is a great solution for needing a brake controller and having two vehicles. I like the Curt Echo Wireless Brake Controller item # C51180 better because you can use your cell phone to control the settings. The major drawback for it though is that it can easily walk away. The Tekonsha Prodigy RF Wireless Brake Controller item # TK94FR gets installed directly to your trailer's frame so it's pretty hard to steal. Performance wise they're pretty equal. The Curt Echo item # C51180 has a better price point. The Trailer Connector Adapter w/ Lamp-Out Sensor Bypass item # 20142 will work with both wireless controllers.
