They cannot possibly mess that up right. I get it off of ebay. I get it in 4′ lengths, which will do a harness. I used to use heater hose, stuff like that, but I find the heat shrink leaves a very professional look. Ill post some pics of the finished product.
Believe this is the one I used, It was either this 2", or maybe touch smaller? Guess depends on the harness you are making. If you shop around, you can find some deals, free shipping.
My local NAPA has large size shrink tube. Have to ask for it as they keep it out back with the Gold. It is expensive, but good to have on short notice.
