If you find a break, replace the wire, don't just tape it up.
Also, you can order this sleeving from McMaster-Carr to resleeve the new cables, the starter harness I made looks like a factory harness with this (and it will protect the cable if it rubs on anything).

Top left of the page, enter 1508T36 and hit find. I bought 15' so I would have extra if I needed to do another harness. Get 10 ft, more than enough and will cost you under $20 shipped.
