Wiring help with HO Alternator Please!!

[Yaris Lighter]

I just received an HO Alternator today and it has only three wires. I'm trying to figure out how to turn the wiring for the old Volt. Regulator four wires into three wires.
I have found a diagram in the Toyota Wiring Manual but I don’t want to mess up (Plus I don't even know if it's the right diagram).
From what I'm guessing so far is this:
HOA's Blue "S" wire to Plug's white wire
HOA's Green "Ing" wire to Plug's Green wire
HOA's Yellow "L" wire to Plug's Blue wire
But I don't know what to do with the Pink wire
If someone can take a look and tell me their inputs; I would really appreciate it! Thank you for all your time!
