instead of using the wire splice methods for speed and ignition advance delimiting, i would prefer to go with a non wire splice method.

one method is to use the hrc harness and hrc delimiter box. will this setup render my lights useless? if so, is there a way to get around this?

another method is to retain the stock harness and use the kiss delimiter box(?). i assume the kiss box is plug and play(?). does this setup produce less performance than the hrc setup? and if so, why?

any other info concerning derestricting the mc21 without wire splicings would be appreciated.
