wiring hd tach on 2012 softail custom
I am trying to install HD mini tach on 2012 softail custom. The tach has 3 wires blk for grnd, red for hot, and pink for trigger. Instructions say to install pink in #3 port on emc but does not have #3 on emc. Have looked over wiring diagram and see no tach trigger or any think close. Can anyone give some help, would be very much appreciated.
