swaping to MSD 6al

Dont go too far without the stock stuff in the trunk. To some guys, MSD stands for May Suddenly Die....I lost one 6A box only a mile from home. Backwards polarity will cause the falling edge of reluctor to trip coil, about 10 degrees out. White lead should be well insulated to prevent grounding and cutting ignition completely (or tie into a anti theft ground switch in cab) or wire into MSD distributor if it calls for an orange to white splice.
