Tape vs split loom
I used a combination of these from Motorcitymusclecar (Inline tube) on ebay
Factory Electrical Wiring Harness Cloth Tape OEM NOS M | eBay
2 Rolls Factory Electrical Non Adhesive Wiring Harness Friction Tape OEM A NOS | eBay
I tried to duplicate factory appearance. As best I recall without looking... The adhesive cloth is used in areas likely to get wetter. Headlight area etc. The non stick was used through the engine bay and I believe under dash. Both are 1 inch wide - easy to use, yet saves a lot of wraps vs 3/4.
Found a few pics with some of it
