EZ wire ignition question

Clarify: Your pink power wire is "ignition run" The MSD has a "LARGE" red and a "small" red. The small red acts like a relay trigger. THAT is the wire you want wired to the pink

The MSD "large red" and "large black" are to be hooked direct to battery, the red of course fused.

The IGN1--IGN2 jumper is correct. The reason for this is that IGN1 "run" goes dead during cranking. The IGN2 used to go to the coil + side of the ballast to provide full voltage for start, IE the coil resistor bypass. So the IGN2 in your case will provide start voltage for the ignition system
