    Wiring feed to pertronix coil &distributor question 67 mustang 351 w

    Would I be able to tap into the pink resistor wire where it starts at the ignition switch and run a wire to the pertronix 
    coil (+ side)? The pink wire feeds the coil and also the starter solenoid,I would leave the pink wire intact to feed
    the starter solenoid only. Or would I have to cut out the pink wire and replace it with a non resistor wire. I have a
    cast pertronix distributor& flame thrower coil. I found out that I had 12 volts at the coil,but I guess it couldn't provide the amps with the resistor wire. I was going to get a power relay to feed the coil, but pertronix said on 74 down ford cars, you have to wire in a one way diode to stop back flow when you shut the key off. I will be putting in a new
    ignition switch while it's apart.  I'm sure this has come before I can use your input. THANKS! mustang stu
    P.S. sorry for the double post last week

    I just bypass that whole deal and go 12V keyed to the coil.  No chance it gets screwed up that way.  Use a 14 or 16 gauge wire for this.

    I tapped into the ignition wire before the pink resistor wire for my Pertronix.  It works fine for the last 20 some odd years.  Now I have both full voltage and reduced voltage wires to use.  I changed nothing else.

    I have bypassed it and also used it to activat a relay to provide 12 volts to the distributor.  I'm very happy with the relay method and no modifications to the wiring harness.
