What 7-Way Wiring Needs to be Ran for Bluetooth Brake Controller on a 2021 Jeep Grand Cherokee L

Question

Question:

I have a 2021 Jeep Grand Cherokee L and bought the 4 way wiring system and the 7way adapter kit. Question is I am running a Bluetooth trailer break system, so do I need to use the blue trailer break wire? I now that to use the charging feature I need to connect the black, just not sure what to do with the blue and yellow wiring?

The Universal Installation Kit # ETBC7 comes with all of the wiring and connections needed for a traditional in-cab brake controller, but since it sounds like you'll be using one of the Curt Echo brake controllers (linked below) you won't need to run the blue wire - you just need to make the 12V power connection for the brake controller to work properly. We actually have a wiring kit built for Bluetooth brake controllers found as the Upgrade Kit # ETBC7L.

Here is a list of the Curt Echo controllers:

- Curt Echo 7-Way Plug Mount # C51180
- Curt Echo In-Line # C79DR
- Curt Echo Under-Dash # C27JR
