Question:
Hi, I have a 2024 Mazda CX5 and a 2016 Chevy Silverado. The CX5 has no type of towing brake controller/wiring. The Silverado has a towing package but does not have the factory brake controller. If I were to put the 4 pin and 7 pin wiring harnesses in the Mazda, would a Curt Echo then be able to run both vehicles trailer lights and brakes? Would I then have lights also? Thanks, Earl MacTavish

Hi Earl,
With the proper set up, the Curt Echo will for sure work with both your Mazda and Chevy Silverado!
To add a 7-way to the back of your Mazda to work with the Curt Echo part # C51180, you'll need to first add a trailer wiring harness like the Curt T-Connector Vehicle Wiring Harness w/4-way Flat part # C45FV to give your vehicle the necessary wiring and a 4-way flat. From there, you can use the 7-way RV Upgrade Kit for Trailer Brake Controller Installation part # ETBC7L that the 4-way flat will plug into and give you the necessary wiring to run a wireless brake controller. The ETBC7L is specifically used for installing a 7-way that works with wireless brake controllers like the Curt Echo and will not work with in-cab brake controllers that mount under/in the dash.
Since your 2016 Chevy Silverado already has a tow package, as long as you have a 7-way you can easily plug the Curt Echo into your truck and make any adjustments straight from the Curt Echo app, OneControl. The Curt Echo works by using an internal 3-axis accelerometer to sense how the vehicle is braking and send the right amount of braking power to your trailer to ensure it slows at the same rate as your vehicle. It will also pass the signal from your vehicle's lights to the trailer so that your trailer and vehicle lights work in synchrony.
What are you planning on towing with each vehicle?
