Alternator wiring

Hi Guys,i know its been done before but just need to clarify one thing.
Have upgraded my charging system using the MadElectrical as a guide.Bypassed Amm gauge.
Got a new 60 amp alternator with 2 field connections.
Original alt had battery post and single green wire.
Car runs FBO electronic ignition and electronic external regulator,one of the old style look with electronic inside.
Have spent many hours reading previous posts on the subject.
Is it just a matter of grounding the second field terminal to the case(alt came with one supplied),
Just need to clarify this before start up.
Many Thanks
Terry
