Default h2b - alternator wiring help 4pin to 3pin

ive done the h2b conversion to my 96spec integra type r

ive used the h22a7 accord type r engine

the wiring on the engine loom that i have has 4 wire on it.

the new alternator that im using is a d series one from a 88-91 civic/crx with 3 ribs on the pully to create extra clearence from the chassis

now the problem is i dont have the plug / wiring for the new alternator. this new alternator has 3 wires and the old alternator has 4 wires

now i need to rewire it but i dont have any wiring diagrams or pinouts

does anybody have any or can tell me what each terminal does.

here is a picture of the alternaot that i have, what does each pin do so i can match it up with the wiringloom that i have.
i know the 4th wire is going to be left unwired which is the ELD wire

just need to know what these three pins are for and which ones are which.

thanks in advance

d series alternator from 88-91 civic / crx
