Hey 11, I've been trying to hook up a tach to my bike, the tach wiring says to hook up the green wire from it to the signal wire. I've been trying to use the Barons 2 into 1 adapter, but I'm getting no signal. My question is, Do I hook up to the black wire on the coil, or the other one that's at the top of the coil? Any feed back would be a big helpI had to change those connections when I had my tank off and was installing tachometer. They were on, but your right AR- they could have used a little more pinch.
