It is difficult to install a traditional brake controller on a 2009 BMW X3, so much so that the best option is to use the Prodigy RF, # TK94FR. It does not involve taping into the vehicle wiring. Instead, this unit plugs into the 7-Way trailer connector and your trailer connector would then plug into the RF.
It uses the power provided from the 7-Way to apply the electric trailer brakes. It has a built-in accelerometer that senses how hard or soft the vehicle is braking and applies the trailer brakes accordingly. The hand-held module that goes along with you in the cab of the vehicle plugs into a cigarette lighter or auxiliary power port socket and is only used to adjust the braking settings on the RF or to apply the brake manually. I have included a link to the installation instructions for reference.
For the RF to work you need to have a functioning 7-Way trailer connector on your X3. You will need to obtain this from your BMW dealer if the X3 does not already have a functioning 7-Way.
If the trailer has LED lights you will also need a special adapter, # 20142, to bypass the bulb out sensors on the X3.
