Electrical Re-Wiring Question

This could also be a restoration question as well...

I am replacing my wiring harness with the EZ wiring kit and wanted to know what you guys used to protect your wiring harness after replacing the old one.

I noticed that the original engine compartment used a vinyl non adhesive tape\wrap and the passenger and truck comparts used a cloth type tape\wrap, this too was non adhesive.

Thanks in advance...
