Technical characteristics of the 5-pin relay

The presented five-pin relay belongs to the Relays category and acts as a switching element in the vehicle's electrical system. The use of five pins enables more complex functions than simple two-pin relays, which is important when controlling circuits that require changing the power path or switching between different loads.

The yellow housing facilitates quick identification of the component in the fuse box or relay module, which is useful during diagnostics, service, and potential replacement. The design, based on a standard pin layout, allows for precise seating in the socket and a stable connection with the electrical harness.

Application in Mercedes models

The relay has been designed for selected Mercedes models from the C117, GLA X156, ML W166, W176, and W246 families, where it is responsible for controlling specific electrical circuits. By adhering to the manufacturer's specifications, it ensures consistency with the factory energy management system and onboard electronics.

The original origin from the Mercedes brand means a perfect fit for the electrical architecture of these models, correct load capacity parameters, and compatibility with factory installation diagrams. This is particularly important in vehicles where multiple control modules work together within a single network.

Benefits of using an original relay

Choosing an original five-pin relay for a Mercedes translates into a number of practical advantages:

• maintenance of factory circuit switching characteristics,
• secure fit to the socket and electrical harness,
• consistency with service documentation and installation diagrams,
• easier diagnostics during future inspections.

The used component allows for an economical repair while maintaining the original specification, which is beneficial both from the point of view of durability and subsequent service maintenance.

Condition, identification, and visual features

The relay is offered as used, which means it comes from disassembly but retains the functionality required for further operation. The yellow color of the housing, marked in the technical data as yellow, facilitates identification in the relay compartment and reduces the risk of error during installation.

Additionally, the product has assigned warehouse identifiers, such as SKU and OEM part number, as well as appropriate interchangeable numbers, which makes it easier to select the correct component based on service documentation or manufacturer catalogs.
