Personally I would not use Pertronics , seen too many failures . Having said that you do not need the electronic wiring harness the pertronics adds ! more power wire , this must go to the blue 12 v Feed wire at the Alt or Ballast resistor , NOT coil +terminal.
My choice would be Mopar performance dist & the new Rev-N-Ator ECU , this would require the new wire harness to have the electronic ign .
