Coil wiring

[rideblue00]

Okay guys, who has an original V8 with the stock wiring? I am having problems figuring out my coil setup. I have an original 327 with the original harness with deluxe gauges. I seem to be missing something on how the coil hooks up. I seem to only have the one side(yellow wire for +side of coil). What color goes on the neg side? Im thinking it was a green wire and also the condenser with a black pigtail that was also connected to a black wire from the orig distr. Im actually hooking up a Mallory Unilite distributor with a ballast resistor and I'm not understanding the Mallory wiring diagram. Maybe a fresh set of eyes on this will help. Hopefully someone has also used a Unilite? Thanks guys.
