(b) Fabricate another ground wire long enough to reach from Pin 9 of the remote switch
plug to aircraft ground.
(c) Fabricate a power wire long enough to reach from the remote switch plug (Pin 1 or Pin
3) to the selected aircraft power source.
(d) Prepare the wires as described in Steps (3)(a) and (3)(b).

(4) Fabricate two wires of sufficient length to reach from the harness ELT receptacle to the
buzzer.
NOTE: These wires provide power and ground for the buzzer. Use appropriate means of
identification for the wires, such that the wires can be readily identified.
(a) Prepare the wires as described in Steps (3)(a) and (3)(b).
(5) Crimp male terminal pins (151-6627) on the harness wire ends at the ELT, as follows:
NOTE: Use Molex crimp tool 63811-3300, or an equivalent tool for 0.062 in. terminal pins.
(a) The ground wire in the same pin as the harness wire designated to terminate in Pin 11.
Make a note of the wire identification for later reference.
(b) On each of the remaining wire ends at the harness ELT end.
(c) The buzzer power and ground wires.
(6) Crimp appropriately sized ring terminals on the buzzer ends of the buzzer power and ground
wires.
(7) Crimp an appropriately sized ring terminal on the airframe end of the Pin 11 ground wire.
