Get a little o-ring that just slips on and slide it on before attaching

connector.
Put heat-shrink over both the cable and the o-ring.

You could do some coding with this -- no bumps vs 1 bump vs 2 bumps.

I like this. I was going to suggest a thin strip of 3M stair tape (like
wing-step tape) under the shrink wrap as a braille-lite device but the
o-ring is simpler and much more versatile.

I'll be stealing this idea immediately.
