Toyota: Need help please with Alternator wiring from 82 Tercel

Hello group..
I am in dire need of someone who has a wiring diagram, or is familiar with
the alternator from a 1982 Tercel, with integrated regulator..This
alternator is not being used for the stock application is why I am seeking
this info..On the back of the alternator, is a three prong plug..The prongs
are marked "L-S-IG" plus the battery wire post..I need to know what needs to
be connected to these, if anything, to make this alternator act as a stand
alone alt similar to a "one wire GM" unit...This is being used on a 1964
Studebaker Avanti, R-1 with AC...I am told the unit is a direct bolt in
replacement and is ten amps higher...Any help would be greatly
appriciated...Thanks group...John Winn, Austin TX
