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.
Most of the newer tachs pick up the digital tach send at the speedometer. The plug that is plugged into the speedo should have an open #3 port. You just pull that little blue lock pin out of the plug housing and you should be able to slide the tach wire right into the open port in plug.
