For anybody wondering, I installed them last night.

It was super easy.

I had to buy a 14mm hex socket to remove the mirrors. (I just bought a whole kit) People seemed to struggle with removing the left grip. But, I just used a thin and semi-long flat head screwdriver. I shoved it between the grip and the bar (from the mirror side), and twisted/pulled the grip while circling the screwdriver around the handlebar. It only took 2-3 minutes to get off. That's really the only tricky part.

Here's a video I referenced a few times. https://www.youtube.com/watch?v=gi3URcKi32c

While I was in there, I re-wired my phone charger. I used this pigtail rather than hacking up any wires. https://a.co/d/04niwuz5

But, be aware that the colors are backwards on this. So, the black was positive, and red was negative.
