Made each wire up and labled them with small type from a label maker. I think using laser printed paper might work better. If you apply to much heat on the shrink wrap it will darken the label material. I made one black and couldn't read it.
Image 2 & 3) is 11-12318 SPIRAL WRAP WIRE PROTECT 1/8" from ACS. I wrapped it after the wires were run and held the ends with small tywraps. Makes for a clean light wire run.
