Voltage problems, cutting out when hot

It looks like the schematic is the same as 74.

With the key on engine off I’m getting 11.65v at the J2A pin at the ballast.

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.

You guys are what makes this sight an invaluable resource for guys like me.
Mattax, if your knowledge was gold you’d be a Bazillionaire!

Again can’t thank all of you enough! I think this should let me get back to where I need to be.

On another note I pulled all the wires from the alternator started the car and took a reading which read 0.00V.
I’m going to pull it off and have it tested.
Again I have no idea what this actually means but thought I would run it past you guys and get an opinion since it is overcharging (15.77v when hooked up.
(I’m jumping ahead, I know I need to get the ignition and other wiring sorted before concentrating on the alternator.)
