I want to install a remote start alarm. Does anyone have the wiring diagram for a 2004 Monte carlo?
Make sure to verify your wires first and good luck.
| MONTE CARLO 2000-2004 | | |
| WIRE | COLORS | LOCATION |
| 12 VOLTS CONSTANT | RED (2) | IGNITION SWITCH HARNESS See NOTE * |
| IGNITION 1 | PINK (+) | IGNITION SWITCH HARNESS See NOTE * |
| IGNITION 2 | DARK GREEN (+) | IGNITION SWITCH HARNESS See NOTE * |
| ACCESSORY /HEATER BLOWER 1 | ORANGE (+) | IGNITION SWITCH HARNESS See NOTE * |
| ACCESSORY /HEATER BLOWER 2 | BROWN (+) NOTE ** | IGNITION SWITCH HARNESS See NOTE * |
| STARTER | YELLOW (+) | IGNITION SWITCH HARNESS See NOTE * |
| PARKING LIGHTS | WHITE ( - ) | in PINK 24 pin PLUG, Pin A2 at the BCM *SEE DIAGRAM* See NOTE *** |
| DOME LIGHT | BLUE/WHITE (-) and BLUE ( - ) | GRAY 16 pin PLUG, Pin A8 and A1 at the BCM See NOTE **** |
| POWER DOOR LOCK | ORANGE / BLACK (480 ohm Resistor) | GRAY 24 Pin PLUG, Pin B3 at the BCM, (TYPE "B") |
| POWER DOOR UNLOCK | ORANGE / BLACK (Same wire) | *SEE DIAGRAM* See NOTE ***** |
| TRUNK RELEASE | BLACK ( - ) | at the TRUNK RELEASE SWITCH |
| TACH SENSOR | WHITE (AC) | at the IGNITION COIL |
BRAKE | WHITE(+) | at the SWITCH ABOVE the BRAKE PEDAL |
HORN | BLACK ( - ) | at the STEERING COLUMN HARNESS See NOTE ****** |
FACTORY DISARM | LIGHT GREEN ( - ) | GRAY 16 Pin PLUG, Pin B3 at the BCM |
| FACTORY ANTI-THEFT | GM's PASSLOCK II | Requires part # 791 bypass module |
NOTE * The ignition harness is located far to the right of the steering column, behind the ignition switch.
NOTE ** This wire must be powered as an accessory wire. If powered as a 2nd ignition the car will not crank.
NOTE *** The BCM (Body Control Module) is located above the brake pedal. It is a plastic box with three plugs that face the firewall. You must diode isolate this wire from the BCM when doing remote start to avoid the service engine soon light.
NOTE **** The driver door trigger is BLUE (-). The BLUE/WHITE (-) will catch the passenger door. Use both wires and diode isolate both.
NOTE ***** Lock requires a (-) Negative trigger thru a 480 ohm resistor. Unlock requires a straight (-) Negative trigger. Must use relays if the unit does not have on-board relays built in.
NOTE ****** Horn can also be found at a BLACK plug with a BLUE insert above the gas pedal.
This is what I have:
Can use OMEGA # DB-DLM-3 Door Lock Module
OR
OMEGA # DB-GMDL-BP DATA BYpass and Door Lock module
