Compatibility of Curt Echo Wireless Brake Controller on 2020 Subaru Outback XT


Have a 2020 Subaru Outback XT with tow capacity of 3500. Would like to tow my popup. Comes with 4 way. Would like to a 7 way kit and use the Curt Echo wireless controller. Will this system work on my vehicle and what 7 way kit do you recommend I use? Thank you,

The Curt # C51180 Echo would indeed be compatible with your 2020 Outback, and of the available controllers it would be the easiest to install. The Echo plugs into a 7-way trailer connector and would use your smartphone (iOS 8.0+ or Android 4.4+) as the user controls. Since you already have a functioning 4 pole trailer connector, you'd just need the # ETBC7L install kit. The kit includes an adapter to convert your 4 pole into a 7-way and the hardware, wire and circuit breaker needed to connect the 7-way to the positive battery terminal in order to power the controller.

I've linked to a video explaining how the Echo works, as well as an installation video. The install shown is on a different vehicle, but the procedure would be similar for your Outback.

Hello Mike, Can we only connect the 4 pole to 7 pole adapter? In this case, can the wireless brake controller work? I do not care the trailer can not be charged by towing vehicle but want to avoid the challenge to wire the vehicle battery. If the trailer brake can work properly, I am OK enough. Thank you very much. Jian

The Curt Echo needs the 12V circuit to be active - this is how it actually receives power. So you'll still need to run that power wire to activate this pin, whether or not you have trailer batteries that need to be charged.
