Alternator
I need some help with my Alt wiring. Here are the pertinent pages ( I think ) from my wiring harness manufacturers manual 
As you can see the manufacturer of my harness only provides two wires, a # 14 and a # 15.
I see according to the diagram that # 14 goes into the I position of regulator and the # 15 goes into the A section and then doubles back or pigtails off to also go to the Batt. lug as it would appear on my Alt.
I have 5 lugs on the rear of my
Duralast/Alternator (DL7078)
Lug positioning looks similar as the diagram given above except for the extra lug which they do not show on diagram.
Lugs are marked Bat, Sta, Fld and grd.
I was able to get the factory pigtails from the regulators at salvage yard
and the pigtails are different in that it would appear that I and A are linked together already within the pigtail.
They both have this condenser looking deal coming off of one of the wires, whats that all about.
The pigtails do not match in that one of them has a wire coming out of the S position and the other does not.
I am thoroughly confused. Please help me to understand how to wire all of this together. Thanks

The regulator is fairly straight forward:
I - Wire from Ignition switch or exciter wire
A - Wire to Alternator Bat terminal
S - Wire to Stator terminal on alternator
F - Wire to Field terminal on alternator
The condenser is two reduce voltage ripples that affect the radio. As for the one regulator not having a stator wire in the plug is on some vehicle they used it to power the electric choke on the carburetor.
