Get yourself a wiring harness for the stereo. It's a lot quicker and safer than cutting and joining up wires .
DIRECTWIRE™ WIRING INFORMATION - CHEVROLET / IMPALA / 2005 / Security
12volts red (x2)(common 60A) + ignition harness
Starter yellow + ignition harness
Ignition pink + ignition harness
Power Lock ORANGE / black - BCM, gray 24 pin plug, pin B3
Notes: Lock is negative trigger thru a 470 ohm resistor. Unlock is a straight negative trigger. MUST use relays.
The BCM is under the driver side dash, above the parking brake lever.
Power Unlock same as power lock wire
Lock Motor see notes
Notes: Installation of factory keyless upgrade alarm is not recommended on this vehicle because the door lock motor wires rest at approximately 7 volts.
Unlock Motor see lock motor notes
Disarm Defeat see lock motor notes
Parking Lights+ yellow (F), BROWN / white (R) + passenger junction block end of dash
Parking Lights- white - BCM, pink plug, pin A2
Notes: The BCM is under the driver side dash, above the parking brake lever.
Must diode isolate this wire from the BCM to avoid Service Engine Soon light. See DirectFax document 1600 for wiring information.
Hazards same as turn signal wires
Turn Signal(L) lt. blue (F), yellow (R) + turn signal switch
Turn Signal(R) dk. blue (F), dk. green (R) + turn signal switch
Door Trigger dk. blue (L), dk. blue/wht (R) - BCM, gray 16 pin plug, pins A8, A1
Notes: Use both wires and diode isolate each. Have to also diode isolate from the BCM to prevent false alarms. Refer to DirectFax document 1076 for wiring information.
The BCM is under the driver side dash, above the parking brake lever.
Dome Supervision gray - BCM, gray 24 pin plug, pin A8
Notes: The BCM is under the driver side dash, above the parking brake lever.
Trunk/Hatch Pin RED / black - BCM, gray 24 pin plug, pin A11
Notes: The BCM is under the driver side dash, above the parking brake lever.
Have to also diode isolate from the BCM to prevent false alarms. Refer to DirectFax document 1076 for wiring information.
Hood Pin N/A
Trunk/Hatch Release black - BCM, gray 16 pin plug, pin A7
Notes: The BCM is under the driver side dash, above the parking brake lever.

Multiplex
Part #: 456LW
Notes:
Interface Module: Category:
Combo Interface Required:
Yes Type:
Data Bus
Part #: 457GW
Notes: Can use the 457GW to bypass the Passlock II, but it will not control the door locks on this model year.
