I know the turbo engines use a resistor block, but does the late model (140
HP) engines use a resistance wire to the coil or anywhere in the ignition
circuit?
I looked in my assembly manual and nothing is mentioned of it, nor could I
find it in any of the vendors catalogs.

Yes - All Late Models use the same ignition systems, turbo or not. The feed
from the ignition switch leaves the bulkhead connector at the "firewall" in a
resistance wire, identified by a white-ish braided coating. It is inside the
normal engine compartment harness. The wire runs about half way down the
harness toward the coil, makes a U-turn andgoes back toward the firewall and
turns off and goes to the connector that feeds power to/from the starter
solenoid - a two-blade "T" connector. At that point, the braided wire is crimped to
the regular, copper wire that actually feeds voltage to the coil. During
running operation, the power to the coil takes the route I just described,
traveling from the connector through the resistance wire, through the copper wire
to the coil. During cranking, the copper wire in the "T" connector is fed a
full 12 volts from the starter solenoid. Note the 12 volts is not additive, it
just replaces the reduced voltage fed through the resistance wire and the
ignition switch. As soon as the car starts, the starter solenoid opens (one
hopes!) and the 12 volt feed drops off, leaving the reduced voltage to power the
coil during running. - Seth Emerson
