Route the orange wire and the brown wire from the wire harness to the isolators. Cut to length and
install a male slip-on connector on each wire. Double over the stripped wire before inserting it into the
male connector. Double crimp the connector making sure the crimping tool closes completely. Now mate
the orange wire and the brown wire to the female connectors on the isolators. Either wire may connect to
either isolator. Be sure the connectors mate properly. If the tab in the male connector gets bent, it can
wedge itself between the red nylon and the female metal receptacle. This can result in an intermittent
connection after about a month or more. If the connectors are removed several times, the female connector
can become loose. If this happens, use a pair of needle nose pliers and tighten the metal receptacle inside
the female connector. Tie wrap these wires so they do not obstruct the freedom of travel of any

Route the red wire in the wire harness to the aircraft’s 12 or 24 volt main or emergency bus as appli-
cable 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 instrument red power lead.
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
instrument red power lead (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. Also, if the voltage on this line drops below 11.5 volts,
the analog LED's will be displayed at full intensity. Tie wrap all wires so they do not ob-
