The holes for prongs in the back go in order . they need to all be connected except for the last one. the last one is the start position and should be touched off but dont leave the last wire in there or the starter will just keep rotating. Ya have ta understand the positions of the key switch, first turn connects holes one, two three, lights, acc the next turn touches off the starter. See where these color positions are on the plug. Red, yellow black, etc. Ya aint gonna get results losin yer hair. just hook a wire from the first hole to the second. from the second to the third check acc dash lights. third hole to the fourth. its only a three position switch: lock, acc, start.
