I used some vinyl harness wrap I got from Summit Racing when I repaired/modified my harness. It's non-adhesive and very similar to what was used originally. It wraps on very nicely (is a bit stretchy), but takes 2 people to wrap the harness. The starting point is easy enough to secure by sticking it between the wires in the bundle, and the same method at the ending point with a little electrical tape for extra security. I wrapped the whole harness in one length of wrap, with my daughter providing the second set of hands. It took us less than 30 minutes.
