Connector 1 (CN1), 6-Pin Main Harness

Pin 1 Red - Constant 12V positive (+) power input. This wire must be connected. The proper vehicle
wire will test (+) 12V at all times - while the key is in the off position, the on position and during
crank.
Pin 2 Green (Wire Tag: Yellow) – Ignition 12V positive (+) output and input. This wire must be
connected to the vehicle's ignition for remote start and valet / remote programming. The proper
wire will test 0V with the key in the off position, 12 V (+) while the key is in the on position and
12V (+) during crank.
Pin 3 Brown - Siren 12V positive (+) output. Connect this wire to the red (+) wire located on the siren.
To change siren output settings, review Option 1-05.
Pin 4 Red/White (Wire Tag: Green) - Door trigger input. This wire requires negative (-) or positive (+)
trigger door-pins. The proper wire provides a (-) or a (+) trigger only when the doors are opened.
You will need to test the wire for proper polarity and set the jumper on the side of the CM-2300 for
the corresponding polarity.
.
Pin 5 Green/White (Wire Tag: White) – This is the positive (+) and negative (-) parking light wire that
triggers when you lock and unlock the doors and alarm goes off. The polarity of this output is
selectable via a jumper on the side of the CM-2300.

Connector 2 (CN2), 6-Pin Lock Harness

Pin 1 Not used
Pin 2 Violet/White (Wire Tag: Red/White) - Trunk release 250mA negative (-) output. This is an
optional output that will release the trunk. System will unlock doors and disarm alarm prior to
trunk release.
nd
Pin 3 Orange/Black – 2 Pulse Unlock wire. This wire is used to provide the customer with a driver's
priority unlock feature with option 1-04. With the option on the unlock (blue) wire will pulse first
and then orange/black will pulse if the unlock button is pressed again within 3 seconds.
Pin 4 Blue - Unlock 250mA negative (-) output. This is an optional output that will provide a (-) pulse for
unlocking doors. System will unlock doors and disarm alarm. IMPORTANT: You must use
relays to reverse polarity for (+) trigger door lock systems.
Pin 5 Blue/Black (Wire Tag: Green) - Lock 250mA (-) negative output. This is an optional output that
will provide a (-) pulse for locking doors. System will lock doors and arm alarm. IMPORTANT:
You must use relays to reverse polarity for (+) trigger door lock systems.
Pin 6 Not used

Connector 3 (CN3), 8-Pin Harness

Pin 1 White (Wire Tag: Brown/Black) - Horn honk 250mA negative (-) output. This is an optional
output that will pulse the factory horn. The proper wire will show ground (-) while the horn is
sounding.
Pin 2 Blue (Wire Tag: Orange) – Ground when armed output. This wire sends a (-) negative output
when the alarm is armed. It triggers the starter kill relay for the CM-2300. It can also be used for
other options like window roll-up.
Pin 3 Gray/Black (Wire Tag: Blue) – Instant negative (-) trigger input. This input looks for a ground (-)
input when the system is armed/locked. Once it detects a (-) negative signal it will trigger the full
alarm.
Pin 4 Violet (Wire Tag: Black/White) - Dome light 250mA negative (-) output. This is an optional
output that provides a 45 second (-) negative output after system is unlocked for dome-light
supervision. This can also be used to trigger factory rearm. To change dome light output settings,
review Option 2-04.
Pin 5 Gray/White - Auxiliary Input 1 – This wire functions as a negative (-) pre-warn input. It is
selectable based on option 2-12. It can be changed to a negative arm, negative ignition, negative
instant trigger, negative shock sensor bypass, or negative closed loop trigger input. Please refer
to the option tables for details.
