Denso Alternator Installation

i just bought a similar alternator and the circular plug for it, my question is do i have to use my voltage regulator still? i hear people hooking the sense wire directly to a constant hot (starter relay), if this is the case the green wire off the v/r is not being used, that gives me the impression this alt is internally regulated, but i didnt think it was.....? confused..

i have a newer style (vr)
