Route the red wire in the 9-pin wire harness to the aircraft’s 12 or 24 volt RADIO BUS as applicable via an
independent five amp circuit breaker, the UBG-16 must be OFF during engine start. An alternate
method would be to route the red lead to the bus via a five amp in-line fuse. If the latter method is used, a
spare fuse should be kept in the aircraft.
Route the black wire in the harness to a good ground . Tie wrap these wires so they do not obstruct the
freedom of travel of any controls.

Connect the white/orange wire to Electronics International's Intensity Control Pot (CP-1). If a CP-1 has not
been previously installed in the aircraft panel, do so at this time. This CP-1 will dim the display on the UBG
for night operation. If this line is left open, the display will remain at full intensity at all times.
An alternate method is to connect the white/orange wire to the panel light rheostat. When the panel lights are
turned on for night operation the UBG display will dim. With this method their is no guarantee that the panel
lights and UBG display intensity will match.
Tie wrap all wires so they do not obstruct the freedom of travel of any controls.

The white/yellow wire can be connected to an external light (an AL-1 is supplied in this kit), buzzer (ATG-1),
voice annunciator (AV-17), a relay, etc. This wire grounds when a warning is activated in the UBG. The
current in this line must be limited to 1/10 of an amp maximum. Exceeding this limit will damage the unit. If
this feature is not used, leave this line open. Tie wrap this wire so it does not obstruct the freedom of
travel of any controls.
