MSD 8027 Ignition Coil + and - Leads

[Brucha31]

I Have the MSD 8027 Coils I know + is the larger terminal and negative is the small, but on the drivers side there is an extra small connector does it attach to the + or - side ? So I have 1 larger and 2 small connectors.

I did the coil conversion quite a few years ago when I first got my 8, before I did the small block conversion.
I think the third wire might be a ground to the body.
