Brake controller for E70 experiences

[4MoJoe]

I have that controller on my boat trailer and used it for the first time last year. It worked perfectly. There is a wireless transmitter that you plug into a power outlet in the car with a long cable that you use to adjust the brake force, and has the status read out on it.

The box that mounts on the tongue of the trailer is quite large but there was plenty of space on my boat trailer to do it. I've used Tekonsha products for years and have had very good luck.

I chose this route to avoid the hard wiring of the existing controller I had and also because I remember what it took to get this to work on my E53, which it did, but the job was just tedious. I thought, from the research I did on the E70, that I didn't want to go through it again.

So to short hand it, it works flawlessly, I like that I can remove and stow the in car controller as needed so it's not an ugly addition to my dash.

I already have the stock hitch with 7point connector. It is my understanding that I can simply plug in the RF controller mounted on the trailer to that connector and everything should work. All of the complication in this thread and others are around tapping into the wire that pushes a brake signal back to the controller aren't necessary with the RF contoller.

So, I'm hoping someone can confirm that either knows how it works, or is actually using this or a similar controller and can let me know if it really is that simple. Thanks
