bigjim66,
I have some diagrams in front of me...for what it's worth here are some wire locations.
These are for the 6 cylinder engine; The light green and dark green go to the thermo (temp) sending unit.
The purple goes to the "S" terminal on the solenoid.
The blue appears to be a 18 gauge (small) that goes to the big BATT lug. This wire is shown on the V-8 diagram, but not on the 6 cylinder schematic?
For the paper covered wire...I don't know what that is! There are two more wires. Both connect to the "R" terminal (bypass) of the solenoid. One is called out as 20 gauge yellow and it goes directly to the coil.
The other wire connected to this same location is described as 20 gauge white/orange/purple. Your truck might use a resistance wire to the coil as opposed to a ballast resistor, I think your paper covered wire is the white/orange/purple resistance wire.
Your new HEI installation will not require any reduced voltage to the distributor, but will want a full voltage supply that is switched ON from the key whenever the engine is running.
I'm not sure which existing wire will satisfy that requirement. A check with a meter would clarify this, but I think more folks will chime in and probably give you the right answer.
