Stealth Isolation switch

 
Will it suit my car?
Yes - if your car has a battery, this Stealth Isolation Switch will work for you! However, please note it is not recommended for electric vehicles (EVs) 
 
The Stealth Switch vehicle isolation relay offers discreet, high-level security without drawing attention. Housed in a compact, non-descript relay body, it blends in seamlessly with factory components and can be easily concealed in the engine bay or under the dash.—but don’t let the subtle appearance fool you. Inside, it packs serious tech: a 2.4GHz rolling code receiver embedded directly into the relay housing, paired with two included encrypted key fobs for secure activation and deactivation.
 
This isn’t your typical immobilizer. The Stealth Switch operates independently of any existing alarm or security system, making it the ideal anti-theft solution, especially for VE and VF Holden owners.
 
Vehicles are increasingly targeted via compromised OBD2 ports like the VE and VF Commodore. Withour Stealth switch, it operates as a standalone kill switch, completely invisible to would-be thieves and can not be overwritten by accessing the OBD2 port.
 
What is Included?
1 x Stealth 200A wireless Isolation switch
2 x Rolling code key fobs (paired, batteries included)
2 x Power wires (Red+Black) w/ insulated fittings for easy install
1 x Set of Large terminals and copper links for high current isolation.
 
What It Can Do
The Stealth Switch can be configured to interrupt critical circuits essential to vehicle operation, including:
 
Ignition circuit
Fuel pump
Fuel injectors
ECU power supply
 
Or any other critical low-voltage trigger system...
 
By isolating these circuits via remote control, the Stealth Switch prevents the vehicle from starting or running—even if a thief gains access to the cabin or compromised OBD2 ports like with many Holden VE and VF Commodore thefts.
 
How It Works
At its core, the Stealth Switch is a high-capacity, 12V relay rated for up to 200A continuous current, with the intelligence of a secure wireless receiver built-in. Once powered, the relay remains in a default "off" state, keeping your chosen circuit isolated.
Pressing one of the included key fobs sends a unique, encrypted rolling-code signal—recognized only by your specific relay. Once authenticated, the relay toggles to "on", allowing the vehicle to start and run normally.
 
The beauty of this setup is that there are no visible indicators, LED flashes, or noises to give away the system’s presence. It looks and feels like a regular relay—but its function is anything but.
 
Designed for Discretion. Built for Durability.
No external modules or wiring looms that stand out
Relay housing is virtually identical to OEM-style relays
Operates on a secure 2.4GHz rolling code system to prevent signal grabbing or cloning
Includes 2 x encrypted key fobs (Each fob comes with 2 x CR2016 battery pre-installed)
Internal memory retains state even if vehicle battery is disconnected
Does NOT require any SIM cards or ongoing costs to operate, it's controlled via key fob.
 
Installation Notes
We highly recommend professional installation.
Any Mechanic or Auto electrician should be able to install this item.
 
While the Stealth Switch is simple in concept, its effectiveness depends heavily on strategic integration into the vehicle’s electrical system.
 
If you are not willing to pay for professional installation, please do not proceed with your purchase, as refunds will not be provided for change of mind, damage, or issues caused by incorrect installation. 
 
The Stealth switch can isolate a wide range of circuits depending on how and where it is installed, such as:
Fuel pump relay power
Injector power feeds
Ignition switch output
ECU power source
Starter relay trigger wire (recommended, rather than direct starter load)
 
Important: Although the relay is rated at 200A, it is not intended to carry the direct load of a starter motor. Instead, we strongly advise configuring the Stealth Switch to interrupt the trigger wire of the starter motor relay or solenoid.
 
Each key fob comes with 2 x CR2016 battery pre-installed, ready to use.
