Toyota's alternator wiring hasn't changed much since '85 or so. This thread has some good info:

Sounds like you're looking for the red "IG" wire.
The other two wires are white "S" (voltage Sense), and yellow "L" (alternator Light).

I don't have my manual in front of me to verify that the T100 is the same as above, but it most likely is.
