Purpose and vehicle compatibility

The offered door wiring loom has been prepared for Mercedes A-Class W169 and B-Class W245 vehicles, in the version with a front right door. The vehicle placement specified as front – right side means that the component works with factory connectors in the pillar and the door, which facilitates installation and reduces the risk of installation errors. Thanks to a design consistent with the manufacturer's solutions, the wiring loom allows for maintaining the original cable routing and proper installation layout within the door.

Function and role in the electrical system

The front right door wiring loom is responsible for transmitting signals and power between the body harness and the components located in the door. In practice, this means supporting functions such as:

• power supply and control of the electric window in the front right door,
• transmitting signals for adjustment and potential heating of the side mirror,
• operation of the central locking system and door lock sensors,
• communication with control modules responsible for comfort and safety.

A correctly selected wiring loom helps avoid problems with frayed wires, unstable operation of components, or errors in comfort systems. Factory connectors and the appropriate cable length facilitate the trouble-free replacement of a damaged component without the need for soldering or creating additional wiring sections.

Product characteristics and benefits of use

The door wiring loom comes from a Mercedes vehicle, which translates into compliance with factory manufacturing standards and cable routing logic. The item is classified as used, making it an economical solution while maintaining the original design and compatibility. For workshops specializing in the Mercedes brand and users servicing their vehicles independently, this is a practical alternative to new components, especially for repairs after collisions or mechanical damage to the wiring.

Using an original door wiring loom allows you to:

• maintain compliance with the vehicle's factory electrical diagram,
• reduce installation time thanks to ready-made connectors and proper cable arrangement,
• minimize the risk of installation errors resulting from modifications or the adaptation of universal solutions.

Application in service practice

The component will prove useful both for repairs after mechanical door damage and for eliminating electrical issues, such as intermittent power loss to windows, non-functioning mirrors, or problems with the central locking on the front passenger side. Replacing the complete wiring loom is often a faster and more predictable solution than local repairs of individual wires, especially in areas prone to bending, such as the grommet between the pillar and the door.

Because the product belongs to the Other group, it can be used in various service scenarios, including reconstructing the installation after extensive bodywork repairs or when swapping doors between vehicles of the same model.

Support with selection and additional information

Before purchasing, it is worth comparing the vehicle's equipment configuration and placement on the vehicle with your existing wiring loom to ensure the part is suitable for your specific body version. In case of doubt, it is helpful to verify the manufacturer's markings and reference numbers in service documentation or parts catalogs.
