Ensure the emergency override touch-key receptacle is mounted in a visible but reachable spot. Without this, you cannot disarm the system if your remote fails. ⚠️ Important Disclaimer
Permanent +12V battery feed. Connect to a fused constant power source.
The core of the installation involves the primary 16-pin connector. Below is the standard configuration for the Cobra 4160 harness. Note: Wire colors may vary slightly by production batch; always verify with a multimeter.

Connects directly to the vehicle's factory positive unlock trigger wire.
Mount the siren in the engine bay away from extreme heat sources (like the exhaust manifold) and pointing downward to prevent water collection. Route the siren wire through a factory rubber firewall grommet.
Connects to a clean, unpainted metal chassis ground point. A loose ground is the number one cause of intermittent alarm triggering and weak siren chirps.
Wait 40 seconds for the internal sensors to stabilize. Move your arms vigorously inside the cabin; the siren should immediately trigger.
: The dedicated siren output, leading through the firewall to the high-pitched unit mounted in the engine bay. 🔒 Central Locking and Immobilization
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
Purple Wire: Interior Light Supervision (-). An optional connection that turns on the dome light when the alarm is disarmed. The Immobilization Circuit
If your system isn't working as expected, these common problem areas may be the cause:
The Cobra 4160 utilizes a primary multi-pin harness that splits into power, sensing, immobilization, and central locking functions. Below is the standard wire-by-wire breakdown for the main connector. Power and Ground Connections
Connect the red wire to a constant 12V supply. Ensure the inline fuse is close to the power source.
Bonnet/Trunk Switch (-). Connect to the hood pin switch and trunk light switch to trigger the alarm if either compartment is breached. Outputs and Signaling
For a basic install of a Cobra 4160, you’d typically connect:
