This is much better than the plastic loom, but it is not high temp like it says. It will fail around exhaust manifolds and headers. I had to wrap some spots with aluminum high temp insulated loom.

GM used plastic split loom at the factory, and it works well to hide all the wiring colors and keep wires together. They also sell clips/retainers that clip around the loom and have a nub that pops into a hole (maybe 1/4”) drilled in sheet metal, so it holds the loom in place. It’s not very elegant, but it gets the job done and it’s not expensive.

If I already have plastic loom running along most of the path, (for example, the wire inside the frame running to the taillights), I may use black zip ties and just zip the new loom onto the old.

The woven wrap is more common on newer vehicles, and I haven’t used it on my truck. I think it looks better, but the added flexibility might mean you need more retainers to keep it in place if you have a complicated wire routing.

This is the stuff I always used on restos - not cheap but very heat resistant, easy to clean and very OE looking. Used alot on motorcycles (for heat) too. Not split either so more effort to install.

Never cared for the plastic split loom unless its somewhere unseen like in a frame rail - looks great one time - the day you install it - then it begins to collect dirt and looks like crap imo. A PITA to clean too. It disintegrates from heat or just from age. Only use I ever really had for it was areas that a hose could rub - I'd put a section there.

I like the look of the woven cover the best and a nice touch is a short “collar” of heat shrink tubing at the ends to prevent fraying.

That said, I use split loom on my Blazer because that’s what GM used and I just don’t want to taken the time to change it all since it’s not a show truck.

Many GM vehicles used a plastic “gutter” along the top center of the firewall to hold and hide wiring.

I don't see where it says high temperature for the F6 Woven Wrap. The constant temperature range of the wrap is -70° to +125°C / -94°F to +275°F, Melting point +250°C/+482°F
Way to low for use around exhaust parts.

I also used loom.

Definitely minimize and hide it.

What about the wiring from the starter? i know there was a tube that the wires went through but mine does not have it.

There is a 6"~7" tube that attaches to a bellhousing bolt but it doesn't protect the whole run of wiring, it's mostly a guide to keep the wires off of the collector of the exhaust manifold. Beyond the manifold the wiring is typically exposed.

I have the tube and then some high temp heat sleeve from the tube to the solenoid but it's bright silver so it doesn't hide at all.

I bought a complete kit of the Powerbraid woven Aramid/Kevlar loom stuff from Painless when I got a harness. (The "premium" grade, not the standard.) It stands up to heat and abrasion. (Even tested it with a MAPP gas torch.) It's easy to work with and makes a clean-looking job.

In my '72 I had to lengthen some of them but ran them all through the fenders after I protected them with the split loom.

I wonder if i can hide some wiring behind the firewall inside the cab?
