ATX Alternator question

[EL SHO]

For the alternator experts...

I've got an ATX which I replaced the Alt some time ago along with the 3 wire connector.

I know that one wire is for the idiot light in the dash, the other wire is a Sense wire, but the wire in the middle is supposed to be for the Stator.

When I replaced the original pigtail I noticed that the wire for the Stator was not connected to anything so I left that wire the same, not connected to anything.

So, what's that wire really for? Those it really needs to be connected/wired to something?
Does the Stator in the Alt really needs this wire?

"The male connector on the alternator is a three-prong. Lookin at the EVTM (page 12-2) for the 3.2 it appears there are four connections.

Connector C154
(I) - LG/R to the back side of alt warning lite (12v norm operation).
(A) - Y/W to the fusable links, starter and main power (12v fused, allways on)
(mid wire) - terminates and not used"

Great, thanks! So the mid wire (Stator) isn't used at all. I thought my car's harness was missing this.

Yup, the center wire just dies in the harness a few inches in.

I was reading about how an alternator works and all of its components and when I got to the part for the stator I remembered this. Weird that the SHO ALT doesnt need a connection/signal to the stator
