Starting from under the instrument panel, route the circular connector wire harness up to the instrument
mounting location. (See the wiring diagram at the back of this manual). Place the circular connector about
2 inches back from the panel. Tie wrap the harness in place approximately 1 foot back from the circular
connector. This will allow the FL-1 to be connected outside the instrument for calibration. Be sure these

In the wire harness are 3 foot red and black wires used for instrument power and ground. Route the 3
foot red wire in the harness to the aircraft’s 12 or 24 volt main or emergency bus as applicable via an
independent circuit breaker (five amps or less). An alternate method would be to route the red lead to the
bus via a one amp in-line fuse. With this method a spare fuse should be kept in the aircraft.

Connect the backlight wires as follows:
1. It is recommended to permanently power up the digital display backlight.
a) For a 12-volt system connect the white/brown wire to the bus (via the same fuse used to
power the unit) and connect the white/red wire to ground (see Wiring Diagram).
b) For a 24-volt system leave the white/brown open and connect the white/red wire to the
bus (via the same fuse used to power the unit) (see Wiring Diagram).
2. Connect the white/orange wire to the panel light rheostat. This wire will dim the analog LED’s
for night operation when the panel lights are turned on. If this line is left open, the analog LED's
will remain at full intensity at all times. Tie wrap all wires so they do not obstruct the freedom
