I recently replaced my plug wires on my Alpha One Mercruiser I/O 3.0-1990 but when I took it out next it wouldn't run right. When I switched back to the old ones, the boat wouldn't even start. I think I may have mixed up where each of the wires go from the electronic ignition module to the plugs. Can anyone tell me how to tell where each wire goes? Or recommend a site that could help?
