So, we bought the X7 with the expectation of towing our camper.

Since the X7 doesn't have an integrated Brake Controller, like our Denali did, I purchased a Prodigy Wireless Brake Controller.

I can not get the unit to obtain power from the vehicle. BMW confirms that the 1-o'clock pin position (#4 pin) has 12V power, but the brake controller refuses to power up.

I just got off of the phone with Tekonsha, the Prodigy Manufacturer, and they confirmed that exactly what is happening is a result of the unit not getting power. It's a car problem they say.

I am not sure what my options are here. Is there something in the car that is turning the 12V off, has anybody else been successfully able to get a wireless brake controller to work?

Have you tried testing each of the pins with a voltmeter?

I had an aftermarket 7-pin harness on my X5 and had no issues using the Tekonsha brake controller.

Very interested in how people are able to set up their brake controllers to get their X7 tow-ready, since I'll be doing that as well.
