Electronic ignition just arrived and have a question: On the 66, is the  
"resistance wire" the 20 W/R/B wire that goes from the main engine  
connector to the two connector junction with the 20 B/Y that goes to the  
coil ?

The electronics wants 12v and at least initially I plan to keep  the stock 
coil which needs resistance so need a new switched 12v line for  the 
ignition system. Consequently I need to know where the resistance wire  is 
and that seems to be the only logical place.

Suggestions as to  where to pick off switched (hot in run and start) power 
would also be  appreciated.

Well, I like harnesses and plugs. That compartment plug is the ideal place  
to "pick-off" a full 12 Volts - or whatever is left after going through the  
harness. What I would do is remove, from the plug, the single terminal from the  
engine compartment harness, the one that the whitish resistance wire is  
crimped into. Then get a replacement wire terminal, perhaps one for a  larger 
gauge of wire. Remove the original terminal and crimp the new terminal  over both 
the resistance wire end (cleanly stripped) and a new 14-16 ga. wire to  feed 
the Pertronix. Insert it back into the plug and route it around to connect  to 
the power feed wire of the Pertronix. The stock wiring stays in place,  
feeding the reduced voltage to the coil while running, and the full voltage to  the 
coil on cranking. Meanwhile the Pertronix gets full voltage. -Seth  Emerson
