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.

When I first bought my MC21 (30 years ago!) and knew no better, I ordered a set of Ethos expansion chambers from Cycle World in Japan, and they recommended & supplied me with a KISS delimiter at the same time. A few years later, once the wiresplice was "discovered", I took the KISS delimiter off and did the splice, and have been doing so ever since.

In my personal opinion, the KISS delimiter is a great, tidy, plug'n'play [easily reversible] option for anyone who doesn't want to cut into their harness. Although I mention it in the ignition tuning section of the Main Site, I never advocate an M-max box, as M-max are deceitful.
