Technical characteristics and application

The TYCO relay in this configuration is a component designed for use in the electrical system of Mercedes W163, W169, W203, and W210 series cars, where it is responsible for switching selected high-current circuits based on low-voltage control signals. Thanks to a design that meets the vehicle manufacturer's requirements, the proper current characteristics, response time, and operational stability under typical operating conditions are maintained.

The Yellow housing facilitates quick identification of the relay in the fuse box or power module, which is particularly useful during diagnostics and service. The connectors used are matched to the factory electrical harness, allowing for installation without the need for any modifications to the system.

Benefits of using an original Mercedes relay

Choosing an original relay from the Relays group for a Mercedes allows you to maintain the consistency of electrical parameters with the rest of the system. This is especially important in vehicles equipped with extensive electronics, where incorrect starting current values or switching delays can cause errors in control units or unstable operation of receivers.

• Compatibility with the electrical system of selected Mercedes models.
• Factory fit for sockets and harnesses without the need for adaptation.
• Clear identification thanks to the characteristic housing color.
• Can be used in diagnostic and service processes as a replacement element for worn-out relays.

The used nature of the component allows for cost-effective restoration of system efficiency while maintaining compliance with the vehicle's factory electrical specifications.

Selection and installation in Mercedes vehicles

Before installing the relay in Mercedes W163, W169, W203, and W210 models, it is recommended to verify compatibility with the currently installed component in terms of housing type, number and layout of pins, and purpose in the given socket. Proper selection ensures the correct operation of controlled circuits, such as comfort systems, lighting, ventilation, or other receivers depending on the configuration of the specific vehicle.

The installation process itself is usually simple: after disconnecting the vehicle's power supply, simply pull the old relay out of the socket and plug in the new one, ensuring it is properly seated in the base. Thanks to the preservation of factory dimensions and housing shape, the TYCO relay sits stably, minimizing the risk of contact looseness.
