Instead of going by wire colors, go by the old connector, see the diagram below...........Hook whatever pickup wire went to the EXPOSED male terminal on the old connector to the MSD violet wire
I think this is the issue. See attached image. Currently, the male connector from the old harness is hooked up to the MSD green, not violet.
I'll try this out tomorrow and see how it works. Thanks.
UPDATE: Actually, based on the diagram above, it is currently hooked up properly. The green is the old male connector which plugs into female end of the distributor plug (which is negative). So green is going to negative and violet is going to positive. Right?
