Need 72 Nova wiring dash diagram

You'll probably need to buy a shop manual from Ebay. You can get them on CD now with wiring diagrams.

honestly have never seen a complete diag for anything older than 90 even in the manuals- for the time and headache factor would be easier to order a PAINLESS wiring harness- they make full kits for most everything

63 to 72 are the same and only have 2 wires since its a pass through switch , they can go on either post

Below is a link to the wiring diagram you requested, courtesy of http://the12volt.com

Their is a box, remove the cover and starting from the top left the second connector location moving to the right is the one to hook into, make sure that you have the correct wiring harnass adapter for the vehicle, their are two different ones for GM trucks.

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
