As to the materials to make up a harness, there are various sources of the cloth covered wire with proper color trace patterns but with copper wire and modern vinyl isolation along with companies that can weave the thread loom around the wires into the general harness.

It will be interesting to read what earlier restorers of C15TA (s) have done for wiring harnesses.

Good luck and keep us posted
