What is Required to Use Curt Echo Trailer Brake Controller

Question:

Does this wireless brake controller need a brake signal other than what would come from a 4 way line that is part of my factory wiring on my 2012 Mazda CX-9? I have converted the factory 4 to a 7 way connector but wanted to see if that wiring is sufficient to operate this brake controller. Thanks!

To use the Curt Echo Wireless Trailer Brake Controller # C51180 your vehicle only needs 12 volt, ground, and turn signals connected to its 7-way socket. What this means is you do not need the brake signal from the 7-way.

For example, if you used a 4-to-7 way adapter such as # 30717, there will not be an output wire from the Echo to connect to, so you could simply tie that wire off, as you can see by the accompanying diagram.

Apart from that the only other thing required is that your smartphone have the following operating systems (OS):

- Apple: 8.0 or newer
- Android: 4.4 or newer

I have added links to a couple video reviews of this brake controller for you to take a look at as well which I recommend checking out.

Hello, One follow up question on the curt echo wireless wiring. Where does the blue lead hook to in the vehicle when I do my wiring? I think the idea of this echo device was to not have a brake controller inside the vehicle? Thanks

You're right, the idea of the Curt Echo # C51180 brake controller is that you do not have to have anything inside your vehicle; you will simply use your smartphone to control the device via an app, meaning there will not be a blue lead (brake wire) to hook into your Mazda.
