Setup and Installation
Professional installation is highly recommended for the Viper 3100VX security system. Improper installation can lead to vehicle damage or system malfunction. This section provides general guidelines; refer to the detailed wiring diagrams included with your product for specific connections.
Main Control Module Placement

The main control module, shown in the image, should be mounted securely inside the vehicle's cabin, away from direct heat or moisture. Choose a location that allows for easy access to wiring but is not easily visible to potential intruders.
Ensure the module is mounted in a location that does not interfere with vehicle operation or safety systems. Avoid placing it near moving parts or areas with excessive vibration.
Wiring Connections
The system requires connections to your vehicle's power, ground, ignition, door triggers, and parking lights. The Viper 3100VX is designed to utilize your vehicle's factory horn for alarm output, eliminating the need for an external siren.
- Power and Ground: Connect the main power wire to a constant 12V source and the ground wire to a solid chassis ground point.
- Ignition: Connect to a wire that provides 12V only when the ignition is on.
- Door Triggers: Connect to the vehicle's door pin switches to detect door openings.
- Parking Lights: Connect to the vehicle's parking light circuit for visual confirmation of arm/disarm.
- Starter Kill: The onboard failsafe starter kill feature requires integration with the vehicle's starter circuit to prevent unauthorized engine starting.
Shock Sensor Installation
The Stinger Double Guard Shock Sensor detects impacts to the vehicle. Mount the sensor securely to a solid surface within the vehicle, such as a steering column support or a metal brace under the dashboard. Avoid mounting on plastic panels that may absorb vibrations.
Status LED and Valet Switch

The Status LED, shown in the image, should be mounted in a visible location on the dashboard to deter potential thieves and indicate the system's armed status. It flashes when the system is armed.

The Valet Switch, shown in the image, is used to temporarily bypass the security system for servicing or valet parking. Mount it in a hidden but accessible location within the vehicle.
Operating Instructions
The Viper 3100VX system is operated using the included 1-way remote controls.
Remote Control Functions

The image displays the two 1-way remote controls included with the Viper 3100VX system. Each remote features buttons for arming, disarming, and auxiliary functions.
- Arming the System: Press the Lock button once. The vehicle's parking lights will flash once, and the horn will chirp once (if connected) to confirm arming. The Status LED will begin to flash slowly.
- Disarming the System: Press the Unlock button once. The vehicle's parking lights will flash twice, and the horn will chirp twice to confirm disarming. The Status LED will turn off.
- Panic Mode: Press and hold the Lock or Unlock button for three seconds to activate the panic alarm. The horn will sound continuously, and the parking lights will flash. Press any button on the remote to turn off panic mode.
- Auxiliary Function: The AUX button can be programmed for various functions, such as trunk release or remote start (if an auxiliary module is installed). Refer to your installer for specific auxiliary function programming.
Valet Mode
Valet mode allows you to temporarily disable the security features of the system, useful when servicing the vehicle or leaving it with a valet. In valet mode, the system will not arm, but keyless entry functions will still operate.
- To enter Valet Mode: Turn the ignition ON, then press and release the Valet Switch once. The Status LED will light up solid.
- To exit Valet Mode: Turn the ignition ON, then press and release the Valet Switch once. The Status LED will turn off.
Maintenance
The Viper 3100VX security system requires minimal maintenance. Regular checks can ensure optimal performance.
- Remote Control Batteries: The remote controls are powered by 2 Nonstandard Battery batteries. If the range decreases or the LED on the remote dims, replace the batteries. Refer to the remote control's specific instructions for battery replacement.
- System Check: Periodically test the system by arming and disarming it, and by gently rocking the vehicle to trigger the shock sensor. Ensure the horn sounds and lights flash as expected.
- Wiring Inspection: If you experience any issues, visually inspect the wiring connections for any loose or corroded terminals. It is recommended to have this checked by a professional installer.
- Cleaning: Keep the main control module and remote controls clean and free of dust and debris. Use a soft, dry cloth for cleaning.
