alright ive been tring to figure alot of this out myself but i figured i would ask on this because im afraid the 6a might fry the ms II if i hook it up wrong. but i looked in the mega manual and just saw the diagram for a points style ignition. can anyone shed some light on this?

im running an msd 6al/ 2 plug blaster coil with my 8 pin hei and megasquirt. what i did was got the msd plug and play harness, and i ran the 6al with my stock computer that way. when i put the ms in i just left it wired that way. basicly just wire it up the way it says in the msd instructions.
