May not help, but I do know there were 2 different coils used in the HEI. The parts list would have a foot note asking what color the coil wires are.
Common are the red and yellow. The other coil had the red or yellow replaced with a different color (orange?).
Also the module should come with heat paste. Notice how the package has white grease, not clear.
If you jumper in to the red and yellow wires on the first picture, you can read the dwell with your dwell meter.
Okay I know, what's a dwell meter? @Rusty Nail

it's how we got here.Very familiar with the replacement procedure as well but thank you.
My dwell meter is probably older than most folks reading this. Gonna need to dig it out of my tool storage. Probably sitting next to my flathead valve spring compressor...

That ain't necessarily saying anything... I've got tools that are older than me too, lol.

I had to dig around but knew I still had it…. I’ve got the advance timing light around here also.
I didn’t need the dwell function, using the tach works well though when tuning.
