System Overview

The G-BOM505 module has the ability to eliminate all exterior lighting (except DRL’s if activated) to aid in covert operations. When activated, it will eliminate the parking lamps, reverse lights, and the Service Brake lights.

Installation Instructions

Disconnect vehicle battery before proceeding with installation.
WARNING Disconnect the battery to prevent setting a check engine light.

IMPORTANT — READ BEFORE INSTALLATION
It is the installer’s responsibility to route and secure all wiring harnesses where they cannot be damaged by sharp objects, mechanical moving parts and high heat sources. Failure to do so could result in damage to the system or vehicle and create possible safety concerns for the operator and passengers. Avoid placing the module where it could encounter strong magnetic fields from high current cabling connected to motors, solenoids, etc. Avoid radio frequency energy from antennas or inverters next to the module. Avoid high voltage spikes in vehicle wiring by always using diode clamped relays and solenoids when installing upfitter circuits.
CAUTION
All electronic products are susceptible to damage from Electrostatic Discharge or ESD. Ground yourself before handling or working with the module and harnessing by first touching chassis ground, such as the barrel of the cigarette lighter.
G-BOM505 Module
Remove the lower dash panel below the steering column area and find a suitable location to mount the GBOM505 module. Locate the module in an area away from any external heat sources (engine heat, heater ducts, etc.). Do not actually mount the module until all wire harnesses are routed and secure. The last step will be to mount the module.

G-BOM505 Module Mounting
Ensure all harnesses are properly connected and routed, and are not hanging below the dash area. Mount the G-BOM505 module using screws or double sided tape. Reinstall the lower dash panel.

Cluster Control Installation Instructions

When in Blackout mode the module will turn the cluster backlighting off. The following two connections must be made for this feature to function correctly.
Remove Headlamp switch from panel to get to connector C205.

Dim Down Circuit

1. Locate Pin #3 (Brown wire) on C205.
2. Strip some of the insulator and connect the circuit to the Pink Wire pin 2 of the 4 pin Molex connector.

Dim Up Circuit

1. Locate Pin #6 (Yellow wire) on C205.
2. Strip some of the insulator and connect the circuit to the Tan Wire pin 4 of the 4 pin Molex connector.
   Note: If the cluster backlighting does not turn off when in Blackout mode, then the Dark Car feature on the vehicle must be turned on. First put the module in diagnostic mode and verify LED2 is on. If LED2 is OFF go through Dark Car Control steps. If LED2 is ON momentarily ground the Red/White wire. This will enable Dark Car on the vehicle which will allow the cluster backlighting to turn off.

Toggle Dark Car Control (Default = Disabled)

1. Put the Key in the RUN position.
2. Place the transmission in PARK.
3. Press the test button on the module to enter diagnostics mode. Verify the Status LED illuminates.
4. Apply the Parking Brake.
5. Cycle High Beams On/Off 3 times within 5 seconds.
6. All LED’s will flash once for confirmation.

Post Installation / Check List
The following checks must be made after installation of the system, to ensure correct and safe operation. If any of the checks do not pass, do not deliver the vehicle. Recheck all connections per the nstallation instructions.

1. Turn ignition key on (to “Run”).
2. Apply the Parking Brake and Turn Off all lights (High Beams, Low Beams, and Parking Lights).
3. Apply the Black Out Input (Green/White wire or Red/White wire).
4. Verify Instrument Cluster turns OFF.
5. Hold Service Brake and verify the Brake lights are disabled.
6. Turn on Low Beams, this will disable Blackout.
7. Hold Service Brake and verify the Brake Lights are on.
8. Verify Instrument Cluster backlighting comes on.
9. Turn Off all lights (High Beams, Low Beams, and Parking Lights).
10. Apply the Black Out Input.
11.  Place transmission in Reverse and verify the reverse lights are not on.
12.  Turn on Low Beams.
13. Verify that the Reverse Lights are On.

DO NOT PUT VEHICLE IN SERVICE IF IT DOES NOT PASS ALL OF THE ABOVE TESTS

Diagnostics
Diagnostic mode is entered by pressing the test button on the module. The module provides diagnostic LEDs which lluminate according to the following table. There are multiple pages of diagnostics and the page can be determined by the Status LED. Pressing the test button will cycle through the different pages.

Chime Mute Installation Instructions
Yellow Wire Connection
The G-BOM505 kit provides a harness which consists of a white 4 pin connector with a Yellow wire. Connect the yellow wire to the vehicle as follows: Locate the BCM near the passenger compartment. Locate the blue connector C2280E plugged into the BCM and disconnect it. Note the Pin Numbers on the connector.

1. Locate Pin #33 Brown Wire. It will be a 26 gauge wire.
2. Verify with a DVM that there is Ground signal on the Brown wire when the Driver Door is closed.
3. Verify Ground signal goes away when Driver Door is open.
4. Strip a small amount of wire insulation from the Brown wire (do not cut wire) and attach the Yellow wire using solder and tape.

Chimes Mute Post Installation Test
With vehicle in Park, Park Brake applied:

1. Turn Key to Run (do not start engine) and plug the 6 pin Data Link connector into the G-BOM505 module. This allows the G-BOM505 to read the vehicles VIN to verify which vehicle it is plugged into.
2. Verify that the LED’s on the module are not scrolling (meaning it has successfully acquired and recognizes the VIN).
3.  Verify the following chimes no longer sound:
   • Door Ajar Warning Chime – Key in Run (engine on or off), Trans in Park, Door ajar
   • Key-in-Ignition Warning Chime – Key in ignition (Off or ACC), door ajar
   • Headlamps On Warning Chime – Key removed, Headlights on, door ajar
   • Safety Belt Warning Chime – Key switched to Run, driver seatbelt unbuckled. Note: this last chime may sound occasionally due to the electrical architecture of the vehicle. This is normal behavior and cannot be avoided.

Blackout Operating Instructions

System Operation
The G-BOM505 module has the ability to eliminate all exterior lighting (except DRL’s if activated) to aid in covert operations. When activated, it will eliminate the parking lamps, reverse lights, and the Service Brake lights.
ARMED Input
The ARMED Input is used only if the vehicle has Dark Car disabled. These are not ideal conditions for the vehicle to be “Blacked Out” so the ARMED Input will enable Dark Car. If the Input is not “Armed”, the module will not enter Blackout Mode.
Note: The input is not used if vehicle has Dark Car enabled.
Black Out Preconditions:

• Parking lights must be OFF.
• Headlights must be OFF.
• Vehicle speed must be less than exit speed (configurable).
• Vehicle Armed input enabled (if used).
• Momentarily apply Black Out input. (Pin 1 Green/White)
  Once in Black Out mode, the stop lamps and reverse lamps are inactive. The module will also dim the instrument panel cluster to its lowest level.

To disable Black Out, apply one of the following:

• Momentarily apply Black Out input.
• Turn ON parking lights.
• Turn ON Headlights.
• Vehicle speed goes over exit speed.
  To bypass the “exit speed”, hold the Black Out input while driving and the module will keep the tail lights inactive.

Speed Override
The configurable Exit Speed is used for safety purposes and the speed can be set between 5-20 MPH. To bypass the Exit Speed, enter Black Out Mode by momentarily applying the Black Out Input. Once entered, hold the Black Out input and the module will keep the lights disabled at any speed as long as the input is continuously pressed.
