2004 chevy monte carlo bcm diagram

Anyone have a BCM diagram for a 2004 Chevy Monte Carlo?

The dealer might or might not give it to you, depending on their mood.What are you trying to do? Maybe we can help.

I just did a RS in an 01 yesterday, DEI's information was right on target. Here is what they list: DIRECTWIRE™ WIRING INFORMATION - CHEVROLET / MONTE CARLO / 2004 / Remote Start [PRINT THIS PAGE] 12volts      red (x2) (common 60A)       +       ignition harness Starter      yellow       +       ignition harness Second Starter      N/A             Ignition      pink       +       ignition harness Second Ignition      dk. green       +       ignition harness Third Ignition      N/A             Accessory      orange       +       ignition harness Second Accessory      brown       +       ignition harness Notes: This wire must be powered as an accessory wire. If powered as a second ignition, the car will not crank. Keysense      lt. green       -       ign harn or BCM, gry 16P plg, pin B1 Notes: The BCM is under the driver side dash, above the parking brake lever. 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             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 Reverse Light      lt. green       +       passenger junction block end of dash 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. Power Sliding Door      N/A             Factory Alarm Arm      arms on lock with door open             Factory Alarm Disarm      lt. green       -       BCM, gray 16 pin plug, pin B3 Notes: The BCM is under the driver side dash, above the parking brake lever. Disarm No Unlock      see factory alarm disarm             Tachometer      white       ac       Ignition Control Module Notes: On the 3.4L it is on the top center rear of the engine. On the 3.8L it is on the top right front of the engine. Wait to start      N/A             Brake Wire      white       +       brake pedal switch Parking Brake      lt. green       -       BCM, gray 16 pin plug, pin B6 Notes: The BCM is under the driver side dash, above the parking brake lever. Horn Trigger      black       -       BCM, pink plug, pin B5 Notes: The BCM is under the driver side dash, above the parking brake lever. Memory Seat 1      N/A             Memory Seat 2      N/A             Memory Seat 3      N/A             Interface Module:      Category: Immobilizer Bypass      Required: Yes      Type: Passlock II Part #: 1100F Alternate Part1 #: 1100X Alternate Part2 #: 556LW Alternate Part3 #: 555LW Alternate Part4 #: DesignTech 20402 Alternate Part5 #: DesignTech 29402 Notes: Standard on all models. The Passlock II wire colors are yellow, black, and white (not used). When using the 1100F or 1100X, a software change to 1100GM is needed. Interface Module:      Category: Door Lock Interface      Required: No      Type: Data Bus Part #: IM-GMSD-1 Alternate Part1 #: 456LW Notes: Interface Module:      Category: Combo Interface      Required: No      Type: Data Bus Part #: 1700G Alternate Part1 #: 457GW Notes: Can use the 1700G or 457GW to bypass the Passlock II, but it will not control the door locks on this model year.

Right but I wanted a diagram to verify wire location......................ie: Door Trigger      dk. blue (L), dk. blue/wht (R)      -       BCM, gray 16 pin plug, pins A8, A1 ............................................pin A8 and A1

You can always use a meter to verify wires? If you unplug one of the connectors and see a dark blue wire in pin 8 and a dark blue/white wire in pin 1, I would say that's a good chance at being accurate. Not sure how a diagram is going to comfort you any further. And if the dark blue/white has a light blue (park lights) next to it, and the dark blue is next to a black wire (trunk release) then that should narrow it down a little further. Mike

A. You don't need a BCM diagram. You do plan to TEST each wire before connecting to it, right? B. Besides, going to the BCM in those cars is awkward, inconvenient, and unnecessary. As the Impala sells in greater numbers than the Monte Carlo, use the search feature here for the Impala. Door trigger, doorlocks, trunk release, and parking lights can be found in other, much easier locations in the car. Also, when you get the parking lights at the switch, you don't have to bother with that relay-isolation nonsense.

What about using crimestopper's GM-SL data interface module? Is this a  one wire hook up to the purple wire on the OBD2 connector? Can this module do trunk, doors, passlock, parking lights, turn on your defroster? Very easy to hook up or not?

If you read through the installation manual for the GM-SL it shows that it will control door locks, trunk, passlock and parking lights. It also shows that it will not do defroster for that car.
