KISS delimiter is plug and play, and easily reversible. However, it's just an expensive wire-splice, and nothing more. If you want a part you can just fit between the harness and PGM-III, and remove at any time, and you're happy to pay for the convenience, it's a good modification. Personally, I'd just do (and always do) the wire-splice.
