I just installed a Painless harness, which has no wrapping, just wire ties. I used friction tape, which you can find at home centers near the electrical tape selection. It's a cloth tape which has very little adhesive (if at all) but sticks to itself quite nicely. I think the same tape is also sold to wrap hockey sticks so you might find it at a sports store.
in a pinch if you just need a small amount use 1/2-3/4" electrical tape in this manner, pull off a strip of tape,say 30" or so, put some lacquer thinner on a rag, hold the adhesive side against the rag and pull it so the lac removes the adhesive. I usually let the free end of the tape stick to my tool box or something handy and hold the roll in my hand, this way it doesn't tangle. Actually the cheaper tape works better than quality stuff because it is thinner. If you are doing a big job get the correct stuff from NPD.
A special wiring tape is available that does not have any adhesive.
I bought mine at a local Mustang shop and it's approx twice as thick as regular elec tape. Mine seemed to unravel just slightly at the ends so I took a small piece of regular elec tape to hold the end in place.
You can buy the correct cloth tape at Parts Express or Newark electronics for near nothing, and there is black electrical tape out there rated for underhood use. Just wrap it with cloth and hold the ends down with tape, and volia!
FWIW, the cloth sleeving used elsewhere in the car is also available cheap.
The squirrels in my head have spoken.
