wiring loom being unwrapped, I thought it wise to rewrap it to protect it fully. There are 4 obvious
options open to you. This is an example of what I was left with. A mess of unprotected wires.

This particular braid was plastic but you can get metal or carbon braided sleeve.
I'd recommend going for the plastic braid if braiding is the route you choose.

The wires slide through it and the braid is secured each end.
However, sliding the wires through the braid may not be an option in many cases.

Pros: Can look good if finished properly. Available in different colours.
Cons: Larger connectors won't pass through. Not waterproof.
Sprial wrap is fairly easy to wrap around wires and quite cheap.

The drawback with spiral wrap is it doesn't cover 100% of the wiring.

Pros: Easy to apply.
Cons: Doesn't look great. Won't fully protect the wires. Not waterproof.
Convoluted hose can be found on eBay by searching for "Engine Dress Up Kit" if you want different colours.

Convoluted hose has a split seam and can be tricky to fit. This is standard fitment for some of the engine wiring harness.
Pros: Easy to make it look good and like from the factory. Available in different colours. Water resistant.
Cons: Tricky to get the wires in the split. Not waterproof.
The most expensive initial buy but you do get a fair bit on the roll.
Easy to fit, holds the wiring nicely and protects all of the wires if fitted properly.

Simply wrap around and around the wiring loom, always slightly covering the previous loop.
It sticks to inself and self amalgamates to keep water and dirt out.

Pros: Easy to fit. Available in different colours. Water resistant.
Cons: Not waterproof. Not ideal for exterior use. Not very flexible once fitted.
For ease of fitting and quality of finish I'd recommend the Tesa fabric loom tape for internal wiring.
For external wiring, convoluted hose is the best option if a little tricky to fit.
