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.

If you open up the wiring harness and follow the yellow wire you’ll find it’s spliced with a resistance wire. The yellow wire continues on down to the starter.
The other negative side wire is usually black and goes to the distributor.

The yellow wire goes to the starter and supplies 12v to the coil + during cranking. There should be another power wire that goes to the coil + and only has 7 or 8v. Factory coils need a resistor wire or ballast resistor because constant 12v would burn up the coil. The black wire from the points goes to the - side of the coil. I could be wrong( and I usually am) but I think the green wire goes to the temp sender.

Ok yes on the green to temp sensor. 69 C10 LWB yes that other wire to the + side is also one I was thinking about, but not sure the color or where from. My 66 C20 292 has a yellow and some kind of small dia cloth wire both on the + side. I haven't tracked down where that cloth wire goes too.

That cloth wire is the resistance wire and goes to the junction block on the firewall.
