Tach is rectangular and LED...and butt ugly. I will miss having a tach and would LOVE to replace it with an analog tach (but can't find one)...so the orginal question stands.
Any thoughts?
The harness for those tachs plugged in back by the ignition units IIRC.
I wouldn't cut it as you may end up shorting an ignitor. Lift the tank and trace the wiring.
edit....If you have to unplug one of the ignitors (the little black box)...be very careful. Those things are fragile and can be ruined if you aren't careful.
