You will need to dent in your firewall to clear the HEI Distributor. You may also have to change the base on your shaker to a 75 or later Trans Am with a Pontiac engine base. The easiest way to wire your HEI is to run a new wire from the fusebox to your HEI. There already is a 12V hot with the key on only terminal in the fusebox. It may be labeled Ignition. Check it with a volt meter with the key in the on position and you should have 12 to 13 volts. It's been years since I've done this conversion, so i'm going off the top of my head. Just tape up the yellow and black wires to your points dist. and you can always use them if you go back to stock. Or if you want to look stock. put the Pertronix Ignition module in your current distributor and you'll have electronic without smashing your firewall [img]/infopop/emoticons/icon_biggrin.gif[/img]
