Ok so the unit comes with 4 wires:
1) goes to ground on your battery.
2) goes to positive on battery.
3) goes to the front coil wire coming off the coil. Mine has a 4 wire harness that plugs into the coil and the BE/O wire in the harness is the front coil wire on my 883 Harley iron. I removed a little of the wire sheath and soldered the yellow (#3) wire to the BE/O wire on the harness.



Wiring diagram for a 883 iron 2010-2013 can be seen above.
4) goes on to the forward engine mount lot to give you engine head temperature.
