Black Wire - (- Ground Input): This wire’s connection is required for operation.
The Black wire's function is to supply - Ground, which completes the circuitry and
allows the security system to operate.
CONNECTION: Using its ring terminal, connect 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, but the alarm will not function correctly, giving
the impression of a defective control module. The system can partially operate,
so a bad ground wire connection would be suspected. In some cases the alarm
could arm and disarm properly -but not function correctly otherwise.

IMPORTANT: The Black wire attached to the control module and siren
assembly is the antenna wire. 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.

the security system. Connecting this wire will prevent the system from being
armed while the ignition switch is on, and its connection is required if the Valet/
Override is installed for the purpose of allowing the system to be disarmed without
the transmitter (an “Emergency Override”).
CONNECTION: This connection should be made to the primary ignition circuit.
Primary ignition has 0 Volts when the ignition key is in the "Lock", "Off" and
"Accessory" positions; and +12 Volts in the "Run" and "Start" positions. Make this
connection at the engine compartment fuse/junction block, or (less desirable),
locate the correct wire at the ignition system and securely splice the Yellow wire
to it. Another option is to carefully route this wire through the firewall, and make
the connection at the ignition switch wiring harness, being sure to test the target
wire as described at the beginning of this section.
Gray Wire - (Valet/Override Switch Input): This wire is a - Negative input, and
connects to the Valet/Override Switch. This wire and the Pink wire are somewhat
related in function, and also related in routing and connection.
Pink Wire - (Status Indicator Light Output): This wire is a Positive output, and
connects to the Status Indicator Light. This wire and the Pink wire are to routed
from the control unit and siren assembly into the vehicle’s interior compartment.
