Alright so i'm stumped. I purchased an aftermarket tachometer off Ebay to wire into my sportster because I like the looks of it. I got the tach and wired everything into my bike but the Green wire that in the directions it says to wire into the negative side of the coil or CDI. I was wondering if anyone had any idea where to wire this tach feed wire into so that my tachometer does more than make a light.
Thanks, Jon

Negative side of coil is blue/orange wire and yellow/blue wire
Another option would be the tach signal data wire at pin 3 of your tssm (light green/violet wire which runs to pin 7 at the main harness connector and from there to pin 2 at your speedometer
