My pertronix unit went out and I am broke. I do have a complete brand new ignition system dizzy harness and orange ecu box. My harness is a five pin but my box is 4 pin . My question is how should I wire it , use the 5 pin or the 4 pin wiring diagram. Also I currently am not running a ballist resister . From what I can see the resister the cam with the kit is for the 4 .

Just wire it as a 4 pin system and go from there, unless you think you'll be swapping in an old OEM 5 pin box from a junkyard...

Ok thanks . Really just wish I could just get a new point replacement because that dizzy has been recurved

You can swap the springs and vacuum pod from the points to the ei dist.

The problem there is the EI distributor might have a 9R governor and his points distributor might be a 13 or and 11.5 governor making things a little tough for the respring and limiting the curve...also points needs to have a stronger set of spring in it to keep the quick advance from causing points float on a few cylinders at once making the springs a little sluggish compared to the nice slotted loop arrangement the EI distributor has...

Also the points vacuum pod has a different arm configuration than the EI advance pods, these tend to arc in a different path during advance, when used on EI distributors and can pull your gap out of alignment enough to cause a no spark condition (typically the points vac.. pod is a 6.5X vs. say the most base EI advance of 8.5x...so who wants less highway mileage?)

2 cents,
