taping wire - securing non-adhesive tape

So I am in the middle of a dash wiring project. I bought a roll of the non-adhesive black tape to wrap long runs of multiple wires. How best to secure the ends once you are done? What did the factory do?

The factory (I believe) used a tape that is really thin and seems to be somewhat adhesive.
Then there’s what’s called friction tape (My favorite) because it is actually a coated cloth like makeup and adhesive.
For most any tape I like to end it with a small zip tie to keep ends from unwrapping.
