Technical specifications and application

The TYCO relay with a 6-pin configuration is a switching component for low and medium-current circuits, typically used to control electrical loads in the vehicle's electrical system. The use of a multi-pin connector allows for precise separation of control and power circuits, which translates into stable system operation.

The Black housing is made of durable plastic that protects the interior of the relay from external factors present in the engine compartment or inside the vehicle. The pin layout is adapted to the factory sockets used in Mercedes W168, W203, and W211 models, which facilitates installation without the need for system modifications.

Compatibility with Mercedes vehicles

The offered relay is intended for Mercedes vehicles from the W168, W203, and W211 series, which utilize factory electrical solutions based on TYCO components. By maintaining the original geometry and connector standard, this element can replace factory-installed relays in the corresponding equipment versions.

The product has a dedicated OEM part number and associated replacement numbers, which facilitates verification of compatibility with a specific vehicle configuration. Before purchasing, it is recommended to compare the markings with the existing component or service documentation to ensure full compatibility with the given system.

Condition, functionality, and advantages of the used relay

The relay comes from the secondary market, which allows for the cost-effective restoration of electrical system efficiency while maintaining the manufacturer's original specifications. A used component of this type is particularly attractive for older vehicle generations, where the availability of new parts may be limited or economically unjustified.

Key advantages of this solution include:

• factory fit for the electrical systems of Mercedes vehicles from the corresponding body series,
• preservation of the original relay operating characteristics,
• compact, black housing for easy installation in existing sockets,
• possibility of use as a replacement for several reference numbers within the same parts group.

Technical support and additional information

In case of doubts regarding the selection of the correct relay for a specific model or equipment version, it is worth using the OEM part number and replacement numbers visible in the technical specification. This reduces the risk of incorrect part selection and ensures proper system operation after installation.
