Mopar performance alternator 1or 2 wire???

Mancini has this alternator which states that it is 1 wire compatible but I have a later 2 wire external voltage regulator. The pic shows another terminal with a wire from inside it hooked up. IE a ground, I guess. Can I disconnect that wire and hook up the other wire?
They are having a sale till the 14th and I wanna get it but this got me stumped on weather it would work.
Thx for the input. I'm sure someone will know!

Judging from the photo they have added a "non standard' "internal" regulator (the green wire) and grounded the remaining field terminal by removing the insulating hardware

Is your regulator, the one you are considering using, is it 69/ earlier, or 70 later?

If it's 69 earlier you should be able to remove the green/ internal regulator and just hook it up

HOWEVER IF you have done nothing to solve the "typical" old mopar bulkhead connector issues AND the voltalge drop issues from the battery--the path through the ignition switch--and to the factory regulator IT WILL overcharge.

Also a "one wire" needs to have a MUCH larger charge wire than 3 wire systems, because the sensing is on the charge wire.
