On my 94 Ignition module in the dizzy, and spare ignition coil that's what. I keep a spare module in my glove box along with a screw driver for that. My spare coil, I have a ground wire with an alligator clip so I just have to lay it in there and plug it all in. But then again both of these parts failed on me. Hey it's got 165K on it so far so I'm not complaining.
But then again when I had my 69 Charger R/T I had electronic ignition on that one, and carried a spare spark box, and ballast resistor, along with a screw driver.
