This is a very old post that I was looking at for reference. The post incorrectly states that the MSD to dist wires are Violet is negative and green is positive, it is the reverse, the green(MSD) would go to the black (-) Mopar pickup lead and violet(MSD) would go to the orange (+) MP lead. MSD's website shows this. Of course If you wire it backwards you get severely retarded timing, AMHIK! Just wanted to update this for anyone in the future!
