alternator wiring help please
 

I got a new engine harness from Dennis (Timmy2) and the alternator wires don't match. I had three wires when I sent it and now I have 4. I don't have a picture that includes the spade connector. does anyone know where this goes? it is the newer alternator. I replaced the old one so it may have some internal VR or something. I'm not an electrician - I'm just a knuckle dragging mechanic. Help please.

Here is a picture of early external regulator alternator, and the update information when switching to internal regulator.
