Signal Wire For Tach on an 06 street bob?

[Ray galetti]

I am connecting a mini tach on an 06 Street Bob. As such, most bike require that you plug the pink signal wire from the tach into number three port of the speedometer. This is not the case on the street bob. Any idea which wire I need to tap into at the speedometer head on this Street Bob? Thanks very much in advance for any replies.

Ok, people, never mind, I figured it out. You must connect the pink tach signal wire into number three port at the ecm plug in harness.
