(3) Slide the grommet away from the cable and other conductor ends, such that it does not
interfere with soldering the conductors to the plug (150-1130).

(a) Strip approximately 0.15 in. (3 mm) of insulation from both ends of each of the wire.
(b) Dress and tin the bare wire ends to prevent the strands from fraying during terminal
crimping operations.
(c) Solder the jumper wire to D-Sub pins 5 and 12.
(6) Solder the wiring to the D-Sub plug as follows, referring to the wiring diagram appropriate for
the installation:
(a) Harness wires,
NOTE: Make note of the wiring identification and pin location relationships, such that
the wiring at the remote switch end can be terminated correctly.
(b) Buzzer power wire, and
(c) Ground wire.
(7) Fit the plug into a housing half positioning the grommet such that it fits into the recess on the
cable end of the housing, with the raised collar step against the housing inside face.
(8) Install the bracket washers onto the thumbscrews.
(9) Insert thumbscrews into lower housing half.
(10) Fit the other housing half into place.
