Cobra 4160 Alarm Wiring Diagram -

The Cobra 4160 is a modular vehicle security system designed to prevent theft through both audible alarms and electronic immobilization. It typically includes: (ultrasonic sensors). Perimeter monitoring (doors, bonnet, boot). Double-circuit immobilizer for engine protection. Central locking interface . 2. Cobra 4160 Alarm Wiring Diagram Schematic

This connects to the pin switches located in the engine bay or trunk area. 4. Component Placement

1. Negative Triggered Systems (Common on Japanese & European vehicles)

Locate the vehicle's starter wire or fuel pump power feed wire. Cut this factory wire completely in half. cobra 4160 alarm wiring diagram

The Cobra 4160 features internal relays to handle various central locking configurations. Depending on your vehicle’s make and model, you will need to wire the CDL harness according to one of the following configurations:

This connector manages the main power, ignition, siren, and central locking.

Connects directly to the vehicle's factory positive lock trigger wire. The Cobra 4160 is a modular vehicle security

Before diving into the wiring diagram, it's essential to understand the different components of the Cobra 4160 alarm system:

Verify the connections on both Yellow/Green wires. Check the inline fuses dedicated to the indicator outputs. Double-circuit immobilizer for engine protection

The car's immobilizer is a primary security feature. If the car won't start, it's often due to the alarm system. First, ensure the alarm is disarmed using the remote. If the problem persists, check for shorted or damaged wires in the alarm system, especially near the starter interrupt, as this can directly cut off the ECU or fuel pump.

| | Function | Description & Key Considerations | | :--- | :--- | :--- | | Red | Constant 12V Power (+12V) | The primary power source. Must be connected directly to the vehicle's battery positive terminal via an in-line fuse (e.g., 15A-20A) for safety and reliability. | | Black | Chassis Ground (GND) | The ground connection for the entire system. Connect securely to a clean, bare metal point on the vehicle's chassis, ensuring a good electrical contact. | | Green/Red | Ignition Input (+12V IGN) | This wire detects when the vehicle's ignition is turned on. It must be connected to a 12V source that is only live when the key is in the 'ON' or 'RUN' position. Connect this wire via a fuse. | | Yellow (x2) | Left & Right Indicator Output | These wires output a 12V pulse to flash the car's turn signals when the alarm is armed or disarmed. They are typically connected to the positive wires of the left and right indicator circuits. | | White & Brown | Central Locking Control | These wires interface with the vehicle's central locking system. Depending on the vehicle, the alarm may send a positive (+) or negative (-) pulse. Connecting these to the correct wires in the car's central locking system enables remote keyless entry. | | Red/Yellow | Starter Interrupt | This wire is part of the immobilizer circuit. It is usually spliced into the vehicle's starter wire and cuts the circuit when the alarm is armed, preventing the engine from cranking. |
