Pertronix's with Chrysler Electronic Igntion... ... compatible?
The pertronix is a complete self contained ignition, it contains the control box and pick up in one module. It does exactly the same thing as the magnetic pick and seperate control box in the mopar system.
Since it is self contained there is no way to get the signal to trigger a mopar ecu, plus there would not be any advantage if you could.
You could use the wire from the Pertronix that normally attaches to the negative terminal on the coil to trigger an MSD box if you feel the need for a hotter ignition system.
