Voltage problems, cutting out when hot

I got in a little bit agao and am a bit heat fried. This one I can answer quick.

Am I correct in assuming that since I’m running an orange box (4 wire) that J4 is not being used therefore I can eliminate the 5ohm ballast resistor from the 4 pin and only use (with correct sides of the plugs) the MSD .8 and ditch the 4 pin ballast all together?

This is what I was actually hoping to do as I knew there was a difference in the 4 and 5 pin ECM’s but couldn’t find (figure out on my own) how the circuits worked.

Correct. The 4 pin ECU does not use the 5 Ohm resistor. I don't think it makes a difference if its phyically removed or not -except if removing it means loose wires, then leaving it there is better.
The 5 ohm was originally used to keep the ECU from drawing too much current. I've not figured out how internally that worked. Someone with more knowledge and experience with transistors and circuits probbaly could if they were interested enough. But the bottom line is you don't need the 5 Ohm.
