Anyone know which wires from MSD go to b and c terminals on module of the dizzy?

C is the - side of the coil and B is the + side on a regular setup. I'm not sure how that relates to the MSD.

msd white is trigger - to c msd red to b + ,msd black to coil - , msd orange to coil + The white msd wire in the instal instructions shows use with points or original ignition amplifier - wire. Page 22 in the msd literature shows general import wiring using amplifier with above wire connections.

see if this helps

what about the positive b terminal on the dizzy module,is it spliced with red from MSD and the switched 12v source?
