I just did this (again) and it will be the last time. It takes a lot of time picking through the harness and changing the layout for it to look nice.

Basic harnesses are pretty reasonable in price. I have hundreds, if not thousands, of hours wiring experience and it doesn't seem worth it to reuse 25 year old wire/connectors.
