Well,what's done is done...
At the time of the install I was having a hell of a time just trying to get to the low-beams. In fact I was afraid of breaking the H clips that I actually went out mid-install to purchase a set of standard H7 bulbs just in case I lost patience and nerve. In the pictures in the DIY you had a grommet that was flat and look relatively simple to slide through the H clip, not to mention that your rubber grommet was able to slide on the wires, mine was a multi level grommet that was over half an inch tall and seemed impossible to slide on the wires without tearing;

Just look at the size of the grommet next to the bulb, that definitely wouldn't fit through the H clip. Overall though I had plenty of silicon on hand to patch up any openings into the headlight assembly so I'm covered there.
I'm just glad that this whole ordeal is over, and all I need is a pair of new low-beam dust covers in case I ever want to revert back to a stock set up!
