The four pin ballast is for electronic ignition. Your new wiring harness probably has an ECU connector as well. I would get the right harness unless you want to convert to electronic.

If you have electronic ignition already, with a four pin ECU then a two pin ballast will work. The other two wires in the ballast connector do nothing with a four pin ECU.

4 pin balladt were designed to use with 5 pin ECUs. Have not seen a 5 pin ECU in years.

There are two ways to go. You could just connect the two correct wires to your ballast and call it done. Or you could install a dual ballast , and plug in the connectors the way they are. It might look cleaner. That way you could also run a 5 pin ECU. If your ECU quit in the middle of nowhere and the only one you could find was an old 5 pin, then it would work.

I just feel if I put a 4 pin ballast someone will say-thats not right for that car. Got to love people.

Unless its a 72 dont worry about it. First year for it anyway in 73 they went to the 4 pin..
