Installing a Tow Hitch. Need some help.
I've spent hours researching this without any certainty and can use some input.
MY GOAL: Use my 2012 X5 35i as the tow vehicle for my track car. The trailer being used will have electronic brakes.
Every walk through I've read shows that a hitch and OE wiring harness are required, along with some coding. Simple enough. Yet there is no mention of a separate brake controller required to control the electronic trailer brakes (every other vehicle I've ever seen requires a brake controller). Even my mechanic said a brake controller is not required(???). This is confusing to say the least.
Can anyone who has done this install clarify as to what exactly is required and hopefully clear the air for those seeking answers on this going forward?
(I've emailed Invisihitch and am awaiting a response)
