12/71 build date.. So, probably factory points car...and at some point a conversion was started on this car (distributor), but that's as far as it got.. I see no evidence of any mods to harness..
Okay, so it wasn't already electronic ignition, it just had an electronic distributor in it that wasn't connected to anything?
Then you just need to follow the instructions in your new conversion kit to get it wired up, or follow @Mattax 's nicely done instructions above (assuming it's a newer kit with a 2 connector ballast and not the older four connector ballast kit...).
