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-2305
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-2305.
