J....looks to be a simple solution to avoiding any of the wiring hassles with installing a brake controller in our 2016 Touareg TDI......
Not sure I understand all the fuss people make about the "wiring".
It's 4 wires.
- You can splice directly into them if you don't want to use the OEM style plug, and don't want to make your own harness.
- you can buy an already made OEM harness off Ebay
VW Touareg Plug and Play Trailer Brake Controller Harness
Regarding the unit you've shown.... I personally don't like having to operate it off my phone. I like having the brake controller under my dash, as it makes it easy if I want to quickly apply the trailer brakes, or if I only want to apply the trailer brakes, or if I want to make adjustments, etc. I realize that the app has the same capabilities, but if you're trying to make an adjustment on the fly or in an emergency situation, you don't have time to flip through options, etc..... having a dedicated scroll wheel and quick action lever is much more convenient IMO
