The KISS delimiter is by far the simplest solution for an MC21 wire-splice, and definitely worth fitting if you don't want to cut and splice your standard harness.

Any modification requires checking the jetting, and this is no different. Put it this way, you're releasing approximately 15hp (around a 35% increase over stock) from the motor. You'd be mad not to check the jetting!
