What Wire Covering?

Summit has some pretty nice braided split loom, looks way better than the plastic stuff, it's available in various sizes, I like it alot, needs no tape either

Yup. It's not expensive and you have some colors too.

Also, for end of braided loom or to wrap wires/connections I use DEI quick fix tape. https://www.summitracing.com/int/parts/dei-010491/overview/ Or equivalent.

Sticks well to itself, high temp and water resistant. Was developed for Army. Can even use to make a belt in emergency.

I also use it to wrap and protect wires, hoses or lines that may rub at certain points. Just extra insurance.
