Default Need some wiring help after a 15 year lay off!! 76' Lemans 350 CID Pontiac TH 350

"Ever take something apart and think to yourself,....I don't need to write any thing down I can remember where everything goes?" (15 years ago we didnt have cell phones with cameras so that was not an option!)

And then life happens and 15 years later its time to put things together and you just cant seem to remember where everything goes!

I have a few questions.

We have replaced the 350 with a built 455 out of a 76 GP.
We decided to upgrade the pully system and decided to go with a 140 AMP CVF one wire alternator. Question 1,..... what do you do with the plug in 2 wire lead that normally plugs into the old stock Delco unit, and I would guess that the original lead that you bolted on the stud coming out of the alternator would be the one that I now connect to the one terminal CVF alternator?
The CVF alternator has a wiring diagram with it, should I abandon the wiring in the original harness and just go with their design?

Question # 2 We have replaced the original starter and solenoid with a new gear reduction high torque starter. The new starter has a large lead for the battery cable and only one other small terminal. So looking at my wiring harness it appears that I only have one lead that goes to the starter with a small sta-con connector. I would guess that this would go to the small terminal on the starter, the other cable is the battery cable which obviously with the large sta-con connector connects to the large terminal on the starter.
So in this instance how does the wiring harness get power? It seems like I am missing a lead somewhere? Did the 76' Pontiac engined cars have any additional leads that should be connected at the starter?

We do not have the original battery cable so I do not know if the cable had a lead on it and then that lead sent power to the harness? I dont know.

I would appreciate any help that other A-Body enthusiast might offer on this subject.
