Cobra 4160 Go to product viewer dialog for this item. is part of the Bridge 4100 series

of vehicle security systems. While the exact model "4160" often refers to components within older Ademco systems in some contexts, the Cobra 4100 series

is a modular car alarm designed for universal vehicle fitting. Cobra 4100 Series Wiring Overview

Standard wiring for the Cobra Bridge 4100 series typically follows these core connections based on the Cobra 4100 Fitting Manual and related 8185 Universal Guides Power & Ground Red Wire (+30):

Constant 12V positive feed. Connect this to the inlet side of the vehicle's fuse box. Black Wire (-31):

Main chassis ground. Connect to an existing factory earth point or directly to the negative battery terminal. Ignition & Monitoring Green/Red Wire (+15):

Ignition sense. Connect to a wire that provides 12V only when the ignition is in the "ON" or "Cranking" position. Blue Wire: Direct contact circuit for the boot (trunk) switch. Blue/Pink Wire: Direct contact circuit for the driver's door switch. Indicators & Sirens Yellow Wires (x2):

Connect these to the left and right indicator (flasher) lamp positive feed wires. Yellow/Blue Wire: Dedicated connection to the siren/immobilizer code wire. Accessories Brown Wire:

Switched negative output used for optional sensors like radar modules; it becomes active when the alarm is armed. Grey Wire: Accessory trigger wire for auxiliary sensors. 4100 Fitting Manual | PDF - Scribd

The Cobra 4160 is a modular car security system commonly found in vehicles like the Toyota Hilux, Fortuner, and Nissan Navara. It typically includes a main alarm unit, remote controls, and often an emergency "touch key" for manual override. Cobra 4160 Wiring Guide Draft Review: Cobra 4160 Alarm Wiring Diagram Overview

While the exact 4160-specific diagram varies by vehicle application, Cobra's universal wiring standards for modular systems generally use the following color codes: Power & Ground

Red: Main +12V constant power (connect to the battery through a fuse). Black: Chassis ground (-).

Green/Red: Ignition sense (+12V when the key is in the "ON" or "Start" position). Lights & Siren

Yellow (x2): Direction indicators (connect one to the left and one to the right indicator circuits). Yellow/Blue: Siren connection. Triggers & Sensors Blue/Pink: Drivers door switch trigger. Blue: Boot (trunk) switch. Black (loose wire): Bonnet (hood) switch.

Grey: Accessory trigger for optional sensors like radar or ultrasonic modules. Outputs

Brown: Switched negative output (active when the alarm is armed; used to power additional sensors). Brown/White: Window closer output. Proper Features of the Cobra 4160

Input Triggers and Ignition

• Pin 10 (Pink): Ignition Sense (+12V Input)
  • Function: Detects when the ignition key is turned to the "ON" position.
  • Connection: Connect to the vehicle's ignition coil circuit or fuse box output.
• Pin 11 (Blue): Door Trigger (Negative Input)
  • Function: Detects door opening.
  • Connection: Most modern vehicles use negative trigger door switches. Connect to the vehicle's dome light supervision circuit. (If the vehicle uses positive trigger, a relay is required).

(-) ------------------- Black (6-pin #2)

IGNITION SWITCH
Constant 12V ------ Red
Ignition Run ------- Yellow (6-pin #3)
Accessory --------- Orange (6-pin #6)

STARTER INTERRUPT
Car's Starter Wire (from ignition switch) ---- Cut in half:

• Key side --------- White (6-pin #4)

Part 7: Troubleshooting Common Issues

Even with an accurate Cobra 4160 alarm wiring diagram, things can go wrong. Here are fixes for common problems:

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Alarm won’t arm (LED flashing fast) | Door or trunk trigger open | Check green/blue/violet wires. Temporarily disconnect to test. | | Siren chirps but starter kill works | Incorrect yellow ignition wire | Re-test ignition wire: must be 0V when off, +12V when key in ON. | | Parking lights not flashing | White wire voltage too low | Use a relay to isolate from alarm output (some cars require 12V, not ground). | | Alarm triggers for no reason | Shock sensor too sensitive | Turn sensor pot counterclockwise. Check violet hood pin wire. | | Remote range is poor | Antenna not extended | Ensure coiled wire inside module is straight and away from metal. |
