I used to make up and install my own wiring looms, in jigs that I designed... I didn't lace them, I made them in the time-honoured way that automotive looms were made with electrical insulating tape.
The time-honoured method was wrapping with pitch-impregnated fabric cloth tape similar to friction tape, or to pull it through similar cloth braid tubing and stretch the tubing tight.
After that was introduced plain PVC ribbon which had no adhesive, typically 1-2" width that was heated with hot air as you stretched it around the wire bundles so it pulled tight as it cooled. This ribbon was thinner than typical electrical tape, as it was intended to be wrapped such that there would be 3 layers when done. While some manufacturers did use electrical tape to tie off the ends, it was usually looped under itself and tied off, then the end sealed with cement so it couldn't back out.
I've done all 3 types making custom and replacement harnesses for cars & trucks. Also spent a summer working in a quarry rewiring Cats for electric start and GM alternators. Learned a lot about working with huge-gauge copper there.

Yep, also worked a lot on Cats, Detroit's, Cummins, Gardeners, AEC, Bristol, Leyland, Priestman and Ruston Bucyrus engines on anything from trucks to buses and onto earth movers and huge great excavators, in some pretty inhospitable dangerous locations. Looking back, many of which would be outlawed today as unsafe work places. Oh the things we used to do in our youth eh?
