MSD 6AL Wiring

Rule of thumb is "same size as there." 16 or 14 would be fine. There is less load using an MSD because the ignition wire just becomes a "trigger" (small red to the MSD)

Make SURE with your MSD that you connect ONLY the MSD wires to the coil. No tach, and no radio capacitor

If you are using a magnetic trigger dist. Make sure the "rotor phasing" is correct
Okay good to know, I"ll grab some 16 ga wire! But yes, the orange(+) and black(-) from box will be the only thing on the coil. I have a mopar distrubutor, so by phasing you do mean that the green(-) from from box goes to to black(-) on dist and violet(+) goes to orange(+) on dist, correct?
