put a pair of cb900 coils on my 550 for the replacable plugwires. The 900 coils have spade type electrical connections where the 550 was hard wired into the coil. Made the necessary changes to the wiring but need to know if it makes a difference if the common bk/w wire goes on the neg terminal or positive. I figure it shouldnt matter but want to make sure before I chance ruining the coils.
