MP electronic ignition conversion kit

Yes, but you need to know if your orange box has 4 or 5 active pins. Measure the resistance from pin 5 to ground. If infinity, it is a dummy. Some later ECU's didn't even have a 5th pin. If a 4-pin ECU (most after-market ones are now), you need just a single ballast resistor (for the coil). I think it is 0.5 ohm for both electronic ignition or points, but could be different PN's. The 5-pin ECU's need the dual ballst (4 terminals), where the 2nd resistor is 5 ohm to protect the ECU itself. I think that was only the earliest ECU's, but rockauto is unclear - showing both single and dual ballasts for all 70-76 cars.

To add more confusion, some coils had internal ballast, so don't need a ballast resistor. I have one labelled "for use with electronic ignition" that I recall taking off a 1980's Ram Van. I am currently trying it on my 65 Newport (w/ electronic ign) without a ballast, and so far I haven't noticed the coil getting too hot, so I expect it has internal ballast. It measured ~2.5 ohm, but hard to measure so low. It appears that most after-market coils today are labelled "for use with external ballast" if they require one.
