OK, si I found out my MSD box has to go back to the maker, so I want to run an HEI module for now.IS this way I am running it ok for the coil???
W/ the crescent facing up, right side to the dizzy. I have the bottom left , or C post to the coil NEG. I have the upper post or B to the coil +, AND a toggle switched 12 Volt power on the same coil POS. Will this be fine for the coils life?
If I WERE to run the B post to a switched 12 V power sourse, What would then connect to the coil +??
Thanks in advance....
Andrew/Kidd

Yep, B+ is switched battery power to both the module and coil. If you use a good 30 amp toggle switch and 12 gauge wire you're golden. The HEI module rides herd on coil current so no ballast resistor is required.
