Red: Chain On!

Not really sure why I pushed off doing the chain for so long.  It actually went so easily, I felt like maybe I was missing something.

Set the wheel as far forward as it would go and ran the chain all the way around.  Top tip: do this with the rear wheel locked in place!

Marked the link that had to get popped out and noted that there was plenty of slack on the chain at that point.

Popped the link, which was as easy as before, and then installed the master link.

Then only had to dial the chain adjusters back a few turns before it pulled out the slack.

Job done!

Also labeled some of the wires in the box, but stopped short of actually shortening anything at this point.
