Electrical gurus.... need help with alternator hookup

3 questions...

I have completely rewired my car from scratch,, on the voltage regulator hook up, I am planning on hooking the ign "on" switch to the blue wire going to the regulator as the excitor..... is this correct??


Secondly I have a later mopar 100 amp alternator I am thinking I Might install. will the 60 amp regulator work with the 100 amp alt or do I need a different regulator?

On the hook up at the back of the alternator which regulator wire goes where? blue / green
