<VV> Pertronix & 1966 wiring harness

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. Padgett

Yes, the "20 W/R/B" is the resistance wire.  AFIK, this circuit is the only 
switched B+ in the rear of the car.  The hard resistance wire doesn't lend 
itself to soldering, so for me, the "easy" place to tap into this circuit is on 
the forward side of the engine harness main connector "18P"
