wiring harness bling
I'm about halfway done with the new wire loom I purchased from cableorganizer.com. Quite an improvement lookswise, and its rated to 1000 degress F.
I'll be using the smaller diameter loom over the rasts nest wires and all the other misc. wires, but that will have to be after I wrap everything in some silicone tape which I get in tomorrow.

Only if they sold clear electrical tape so that I it could be seen.

I just got 3 rolls of the self-fusing silicone tape from mcmaster-carr, roughly $8 for each 36ft. roll. I ordered it yesterday afternoon, shipped it next day, and received it in less than 24 hours. Pretty neat stuff being that I've never used it before, but after wrapping some around my finger and seeing how well it sticks to itself, I'm definitely sold on it.

Looks great, and yeah, I used McMaster-Carr self fusing silicon tape to wrap my new harness, and man that stuff rocks! Touch it to itself and its almost instanly glued/fused.

Your work looks good, Matt, and will definitely be an improvement over the stock wiring.
However, Heat Shrink tubing is the proper thing to use for this application. A friend of mine works for a company that builds wiring harnesses for Formula Atlantic cars, and he's shown me a few of the tricks they use. I'll try to take a photo of a harness that he built for our racecar last month, but for now here's a link to the stuff:

You can find heat shrink at most electronics stores. Radio Shack will have very small quantities, but a good electronics supply will have it in 4-ft sections. It would probably cost $40 or less to insulate all your engine bay wiring with heat shrink, and you'll need to get a heat gun which should cost another $40-100. Heat shrink offers better protection against heat, vibration, and strain. The only reason to use convoluted wire loom (aka split loom, the silver stuff shown in your photos) is for its superior abrasion resistance, for instance when pulling a loom through a firewall or when bending your wires around a sharp piece of metal.

What would be the advantages of using heat shrink over what I'm using? Does it not get really stiff after being in a high heat enviroment for a long time? I was under the impression that since this stuff is resistant to very high heat as well as protecting against abrasions, it was the best stuff to use.
If I had used heat shrink, I would have had to strip the whole harness down. I figured stripping all the original tape off and then just rewrapping it in the silicone tape (500 deg F) and then using this particular split loom (1000 deg F) would provide all the protection needed with a lot of room to spare.
Here's the description of the wire loom.

Bentley Harris ConvoShield™ AL was designed to provide thermal protection for components in radiant heat environments. Bentley Harris sleeving is composed of a nylon copolymer base substrate and a highly reflective coating, this product provides protection for wires, cables, and hoses in applications that have heat source temperatures as high as 500°C (1000°F). Conveniently, Bentley Harris sleeving is slit lengthwise for easy installation.
The reflective surface of Bentley-Harris ConvoShield™ AL is extremely resistant to several industry fluids and also shows enhanced resistance to heat distortion. Because of its unique blend of thermal and insulative properties, Bentley – Harris ConvoShield™ is ideal for protecting wire harnesses in high temperature, confined environments such as engine compartments. Its sleek, reflective surface also provides an aesthetically pleasing appearance.
Tests have shown Bentley – Harris Convoshield™ AL to withstand 1000°F radiant heat for one hour without distortion when placed 1 inch away from a heat source.
Due to the metal coating applied, Bentley-Harris ConvoShield™ AL has been known to provide some degree of static dissipation and RFI shielding.

I used a 1.0" wide by 0.040" thick tapered silicone tape with a guide line to rewrap all the wiring harness under the hood. My harness rebuild project required about 12 rolls of tape and a lot of hours to strip the old oem wrappings off and then rewrap and repair damaged areas.
I got a great deal on EBAY for the tape. Bought a case of 18 rolls at 12 yards per roll for about $40 shipped. I believe it was surplus from Boeing used for their planes wiring harnesses.
Attached a pic of one of the harnesses I did. A roll of tape wrapping with about a 40% overlap doesnt go very far, but it puts on a tight flexible waterproof seal with excellent heat resistance. The stuff is easy to work with - I really like it compared to electrical tape. Also used shrink wrap and that corrugated split wire covering for added strenth and protection in various areas as well.

Im in the Air Force, and thats the stuff that we use to wrap our harnesses when we have to cut them. Good stuff.
