I bought this selection of heat shrink, you'll need the 2.0 mm, 2.5 mm and 3.5 mm. A hair dryer and a plate work well together to get enough heat, a heat gun is better.
If you aren't familiar with a soldering iron I would suggest you just use the spade connectors they provide, with appropriate heat shrink. I cut all those off and replaced them with these. They are much more secure and look less jank. The secula lights have two little spades on the bottom so you would need to make yourself a little adapter between the spade and bullet connectors.
Plan the run of the cable, and then cut it to the right length (with a bit of spare). It will be a lot neater than having to hide excess around the place. I've heard a few people on here have great success using Di2 cable sheaths to run cabling behind fork blades/under top tubes etc.
