You'll need to start with a 4-way like the part # 119250KIT you mentioned which is a fit for your 2012 BMW X5. If your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way.

If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
