2jz alternator control

Hello, i am building my first wiring harness for a bmw e46 2jz swap with ecu master black.

What would be the best and simplest way to control or eaven not control the 2jz alternator? i dont know if theres a voltage regulator inside the alternator.

theres a 3 pin connector on the alternator and i need it to be simple and functional.

i see in the emu software you can control alternators but what would be the best option and how do i go about wiring that?

i just need it to pump out 14 volts at all times thats it.

hello it is not ecu controlled at all
