Question:
Hi I have a 2015 BMW X5 no towing package and have installed the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kitinch and the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation - 12 Gauge Wires. What is the easiest/best proportional brake controller to install if I want to have charging to the trailer Li battery while driving? I was looking at the Curt Echo Wireless Brake controller, but I wasnt sure how the additional required wiring would feed back into the trailer the battery is not accessible from the outside of the trailer.

Expert Reply:
The easiest to install brake controller on your 2015 BMW X5 that has the # ETBC7 installed would definitely be the Curt Echo part # C51180 as it basically just plugs into your 7-way and once synced to your phone is installed. I wouldn't say this is the BEST though. Sometimes people have reception issues with this controller which is why I say that. It still functions fine if it loses signal but for some people it's frustrating. I would recommend the Redarc Tow Pro Liberty part # RED24FR as the best option as it only requires putting a small knob on your dash instead of a big controller and is very reliable.
