grounded output when the system is armed, a negative instant trigger, and
a negative prewarn trigger. The Crime Guard 745i

Main Power Connections -
Make all of the wiring connections, then plug
both of the harnesses into the control module.
Black Wire - (Ground):
The Black wire provides Negative ground for the system; proper connec-
tion of this wire is important.
CONNECTION: Using the correctly sized crimp-on ring terminal, con-
nect the Black wire to the metal frame of the vehicle, preferably using an
existing machine-threaded fastener. Make sure that the ring terminal attached
to the Black wire has contact with bright, clean metal. If necessary, scrape
any paint, rust or grease away from the connection point until the metal is
bright and clean. If the control module has an insufficient ground connection,
the security system can find partial ground through the wires that are
connected to other circuits, and function, but not correctly. As the alarm can
partially operate, a bad ground wire connection would not likely be sus-
pected.
Antenna Wire -
The Black (or Black/Red) wire attached to the control module is the
coaxial antenna cable. Do not connect this wire to anything or the transmitter's
range will be reduced or eliminated. Stretch the Black antenna wire out and
as high as possible for the best operating range. If desired, this wire can be
extended to possibly increase the unit's operating range. The same size wire
should be used (22 ga.), and as a general rule the added length should not
exceed twice the standard length.
