SOURCE: need wireing diagram to change 72 nova over to hei distributor
Hey , just take the positive wire from the coil you are removing and feed it to the + terminal on the HEI dist. cap.the other terminal under there is for your tachometer. If you are mounting a master kill switch in the bumper for drag racing- attatch the kill wire to the tach terminal also.
Thats it you just plug the three wire pigtail from the dist. base(pickup) to the cap and you are off.
Remember firing order is 18436572 in a clockwise direction. to find #1 remove #1 plug and have someone"bump" the engine over while holding your finger over the hole-carefull. then line up the slotted mark on the crank pulley with the big notch on the timing indicator. Good luck

had one break like that! my buddy did the same thing! never figured out what it really was but it came down to it was just pushed past it's last leg. not sure if this is you case i would check the signal wire that goes into the engine bay! what ever you have it hook to like the coil etc... if that is fine i would say it is time for a new one or a warranty! good luck

You shouldn't need a spark box because thee coil is located in the dist. cap. You need to run a 12v switched power source to the side of the dist. cap that is marked dist. if it isn't maked it is the term. that is on the front right of the conector pad. the one on the left is for hooking up a tach.

Order is 18436572. Put the timing mark on the crank at 0 and the rotor should be pointing either to the firewall or the front of the engine. If at the wall, turn the crank one more time and it is now pointing at the #1 wire position on the distributor.
left side cylinders are 1357 right, 2468 wire order is in the direction the rotor turns when cranking.
