I have one of those question that I feel I probably should know the answer but do not. I pulled all the stuff to make the switch to Duraspark II and then I also bought an MSD ignition 6200 module. Now I am trying to figure out how they all go together. I bought the connecting harness to go between the MSD and the distributor. Does this mean that I do not need the Duraspark ignition module? If I do need it, what does it get wired to?
