This is my first post hope someone can help. I have a 1995 Starcraft boat with a 2005 mercury 75 hp 4 stroke. I need to change ignition switch and have a 6 pole Indak switch with the marking letters on it of M I M S C B. I have wires colored as follows 2 x black joined together, 2 x purple joined together, black and yellow x 1, yellow and red x 1, yellow and black x 1, red and black x 1. I have no idea what goes where as someone at a marina yanked wires on me. Any help appreciated
