Fuel Selection and Solenoid Control for Single-Point Systems
This control kit provides fuel selection and gas solenoid control for a compatible single-point conversion system. Match the supplied version to the vehicle wiring, fuel system and connected components before installation.
Control components are only part of a vehicle conversion system. Confirm the package contents before ordering. Do not assume that the regulator, mixer, cylinder, valves or fuel lines are included. See our conversion kit component guide for an overview of the complete system.
What Does the Control Kit Do?
Fuel selection: A two-position switch provides manual selection for the configured petrol and gas operating modes.
Status indication: Indicators show the selected operating mode. Indicator meanings depend on the supplied version.
Solenoid control: The control circuit switches power to compatible gas solenoid valves.
Gauge connection: An external gauge interface is available. Match the gauge supply, signal range and wiring before connection.
Gas shutoff depends on both the control circuit and the connected valve. Switching off electrical power does not itself seal a gas line. The installer must verify valve closure and the shutdown response of the complete system.
Technical Parameters
The following values describe the control electronics, not gas pressure capacity. Use the wiring diagram for the supplied version to confirm electrical connections and load limits.
| Parameter | Specification |
|---|---|
| Application | Fuel selection and solenoid control in a compatible single-point gas conversion system |
| Switch arrangement | Two-position fuel selection |
| Operating current | Less than 500mA, excluding the external solenoid valve load |
| Precharge time | 9 ± 2 seconds; confirm the operating sequence for the supplied version |
| Operating temperature | -10°C to +85°C |
| Gauge interface | External gauge connection; electrical compatibility must be checked |
| Supply voltage and output load | Refer to the wiring diagram for the selected version |
Which Vehicle Systems Can Use It?
Compatibility depends on the fuel-control arrangement, not the vehicle name alone. For a carburetor conversion, check the fuel selection circuit and gas solenoid requirements. For an EFI application, also identify any required petrol injector interruption or emulation components.
Provide the vehicle model, engine type and existing fuel-system details.
Identify whether the intended installation uses CNG or LPG.
Check connector layout, terminal functions and wiring polarity.
Match the solenoid load to the controller output specification.
Confirm the external gauge model and signal characteristics.
CNG and LPG versions require separate compatibility checks. A shared switch appearance does not establish compatibility with both fuel systems. Explore our CNG and LPG conversion kits when selecting the associated system components.

Frequently Asked Questions
Is this a complete CNG conversion kit?
Confirm the itemized package contents before purchase. This page describes the switching and control functions. A complete conversion also requires the appropriate gas supply, pressure regulation, metering and installation components.
Does the switch select between CNG and LPG?
The fuel modes must follow the supplied wiring configuration. For a petrol-to-gas installation, the switch selects petrol or the configured gas fuel. It should not be described as a CNG-to-LPG selector without a specific system design.
Will it work with any pressure gauge?
The gauge must match the controller interface. Check the gauge supply voltage, signal range, pin assignment and indication curve. A connector that physically fits does not establish electrical compatibility.
Does the temperature range mean it is waterproof?
A temperature rating does not establish water resistance. Select the mounting position according to the supplied installation instructions and any documented enclosure protection rating.
Installation and Ordering
Installation requires electrical and fuel-system checks by a qualified autogas technician. Verify the selected fuel modes, indicator operation, solenoid response and shutdown behavior before returning the vehicle to service. Follow the applicable system instructions for leak testing and commissioning.
Send the application details before ordering. Include the vehicle fuel system, required fuel version, connector photographs, solenoid specification and gauge model. Contact us for configuration and package details.
