I've done this on my car.
Connect the brown/yellow (indicator light) wire to the small spade lug on the alternator, and the 1 or 2 brown wires to the big ones.
The green/blk? field wire from the regulator to the alternator is not used, this alternator is self-regulating. Just tape it up.
You can leave the old regulator there to look period correct or just unplug and remove it, it won't affect the alternator and charging.
