aspec_fc

yeap....i've did the search but i still can't find what i'm looking for. my FC's a S5 NA and i intend to go for a jspec swap for multiple reasons and i'm not getting into that. anyways, i also understand that getting a TII harness would be my easiest way out but its really hard to get one on hand. Therefore, some thread has suggested that the NA harness can be modify to fit the jspec.
my question is, in terms of modification to the harness, what is it to be done? extending the wires? adding wires? i'm not good at electrical parts; please be gentle with the words.

THANKS IN ADVANCE!
