The wiring harness that fits your 2011 BMW 328xi is a universal hardwire, the Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT, so there is no specific diagram available (just the universal one from the instructions which I added); however, I have linked the directions as well as a video of this kit being installed on a 3 Series which you can use for reference. This kit does include a circuit tester to ensure you find the right functions of your lights, and the sensors clamp onto your wires so you don't have to do any type of splicing, which is going to ease the install.

Since it sounds like you are going to be doing some towing with your '11 328xi, you will also need a trailer hitch, the Curt Trailer Hitch Receiver # C11033 will work if you have a Sedan. this hitch requires the use of Ball Mount # C45521, and you will need to secure it to your hitch with either Pin and Clip # F-4 or Hitch Lock # C23517 if you want to keep it locked to your hitch and protected. You will also need a hitch ball, either the 1-7/8" Hitch Ball # A-80 or 2" Hitch Ball # A-82, depending on the size of your trailer's coupler.

If you have a Sports Wagon, the Stealth Hitch # SH88VR comes with a draw bar with hitch ball to tow or a 2" hitch receiver to carry a bike rack.
