MSD 6AL Wiring and Ballast
Ok. I tested this all out and I can confirm that in order to run an MSD box in a 4 prong balast system, without the original balast or ECU, you need to combine the two wires on the power side of the balast with the little red wire going to the MSD box.
This is what I have been looking for all along. I missed Steven190's last post which he identifies this.
Unfortunately the MSD instructions do not specify this. They only state to use the + from the original coil.
Here is my rudimentary jumper setup till I fix all my wiring. Use the wires on the power side (coming from the bulkhead, not the wires coming from the ECU).
