For the future; you can simply pull the two wires apart; the jacket will split down the center, giving you 2 wires (one for the ground, and one for the +) that have their own jackets.Installed my kit today. Guide was awesome. My fuse cable was limited in that the grounding wire was glued much together closer to fuse split than yours.
If you remove the interior piece by foot rest, there is a bracket for the hood latch release. I got a small washer and put it between the nut and screw to make sure it contacts metal on both sides. It’s 10mm. It works.
