Pertronix wiring help needed.
I'm installing a Pertronix Ignitor II and Flame Thrower II coil in my 1970 K10. I thought it would be a straight forward install. I came across a weird situation with my distributor feed wire. I was expecting a resistance wire to go from the engine side of the fuse block to the positive side of the coil. What I found was a 12 ga pink wire originating in the cab, at the Ign Unfused lug on the fuse box up toward the back of the gauge cluster where it seems to land on a terminal that I can't see. Then from a terminal right next to it, a 12 ga brown wire comes down and goes through a grommet in the firewall, right to the positive side of the coil.
It seems that someone changed the stock wiring to the coil. What I wanted to do was trace the original resistance wire back to the firewall and replace it with a 12 ga wire, but now I'm not sure what to do. I know the Pertronix needs a dedicated 12 volt ignition feed wire. My concern is that I don't know where the wire coming from the Ign Unfused connection goes to up behind the gauge cluster (above the steering column) without pulling that whole thing apart. Would anyone have any idea? I don't want to just eliminate it without knowing what it is landing on. I also had the yellow wire on the positive side of the coil and also on the starter, that I disconnected. I believe this is the normal procedure as it would no longer be needed. I'm also wondering if there is supposed to be a short jumper ground wire in the distributor that goes from the bottom of the distributor to the breaker plate? I have heard that sometimes they are there, but I don't see one in my distributor.
