Selling a CURT Echo Wireless Bluetooth Trailer Brake Controller. This is an awesome, completely plug-and-play setup that requires absolutely zero wiring or under-dash installation. You just plug it right into your vehicle’s 7-way blade connector, download the OneControl app on your phone, and you have full proportional brake control. Only used a handful of times but our new set up doesn’t require it. Save some money and buy this one for $150 instead of $290+ for a new one.
