Mods made by P.O. What do I have with this engine bay harness?

Why?

I'm going to run HEI ignition. I was going to put the module the designed to drive brakes that goes under the dizzy, but I don't want to pull the distributor if anything happens to the module. I have decided to mount the module inside the hollowed out Chrysler ignition box.

Misty was built in June of '74

Was it these or the larger style bumperettes? Starting a bit of a 'study' on when some of the changes were made for at least 74-75. I think I will start a spreadsheet... Your seeing it just on a couple pieces of the electronics. I've looked at a lot of pics, but without knowing build dates some of it seems completely random.

Interesting... I would have guessed the other ones. Exactly why I want to research it a bit. Will probably do a 'fact gathering' thread on here when I get it organized and decide what other changes I want to track

Hum
I have 12 bolts at the + side of
The coil and the red lead of the hei during crank and run but no spark.
What component is bad?

This is exactly how it's set up
