all straight forward, the most awkward pipe is ABS to front passenger side wheel....

S2000 modulator if you don't mind losing TCS, it's physically the same unit, with just one wire position change in the main connector...

adapter harnesses should be plug n play, maybe a tweak for the dash light depending on the original car configuration... and some need an extra connection for the ABS computer reset wire.

think Mita does a kit, SOS does one too, (obvs spec RHD) or party pack order from amayama and the like, but you still need the aftermarket harness adapter.. not sure if Christian at ATR does a kit, tho i know he got a delivery of NSX spec modulators recently
