You identified one of the available 2-inch Class III trailer hitch receivers offered for your 2014 Mercedes-Benz GLK 350, part # 75774 from Draw-Tite. Of the three available options this is the hitch I suggest based on its capacity and lower price. I have linked the written installation instructions along with two helpful articles on hitch installation.
With this I suggest the etrailer Ball Mount Kit # 989900 since it includes two ball mounts with varying rise/drop as well as both 1-7/8- and 2-inch hitch balls along with the pin and clip, all together in a handy bag. This will cover your needs for a range of towing applications.
For a confirmed wiring harness fit for your 2014 GLK 350 you can use # 119250KIT from Tekonsha which is a clamp-on installation with no wire splicing required.
