Purpose and vehicle placement

The presented wiring harness belongs to the Wires, harnesses, and connectors group and is specifically designed for installation in the rear right door of the vehicle. It is responsible for transmitting signals and power between the body wiring and components located in the door, such as actuators, window controls, and other electrical receivers specified by the manufacturer.

The dedicated placement on the vehicle: rear – right side allows for proper cable routing, minimizes the risk of insulation abrasion, and facilitates correct positioning of the harness in factory mounting points.

Technical and functional characteristics

As an original component for the Mercedes brand, the wiring harness is prepared to work with factory connectors and control modules in the C Class W205 model. The connectors used are matched in shape and pinout to the door installation, which reduces the risk of assembly errors and eliminates the need for installation modifications.

The harness supports typical electrical functions provided for the rear right door zone in this model, ensuring:

• a stable electrical connection between the door and the body,
• adequate current capacity for door-mounted receivers,
• compatibility with factory mounting points and grommets.

As a result, the installation process is orderly, and the entire system maintains parameters similar to factory solutions.

Component condition and service application

The offered wiring harness is a used component, making it a cost-effective solution for post-accident repairs, replacing damaged door wiring, or restoring electrical functionality after mechanical interference. Choosing an original, used harness allows you to maintain consistency with the vehicle's factory electrical architecture without the need to adapt universal wires.

The product is particularly useful in situations where wires have been broken in the door grommet, connectors have been damaged, insulation has melted, or when completing a door assembly after bodywork replacement.

Benefits of using an original door harness

Using a dedicated harness for the rear right side in a Mercedes C Class W205 provides a number of practical benefits:

• Factory fit – compatibility with the original electrical installation, with no need for wire modifications.
• Predictable door system operation – correct communication with control modules and door equipment.
• Simplified service installation – connectors and wire lengths adapted to the specific mounting location.
• Consistency with service documentation – ability to use factory electrical wiring diagrams.

For workshops and private users, this means shorter repair times, lower risk of errors, and the preservation of the high-quality workmanship characteristic of the Mercedes brand.

Part selection by numbers and additional materials

For precise selection of this harness, you can use the OEM part number and available interchangeable numbers, which facilitates verification of compatibility with a specific equipment version and vehicle year. It is worth comparing the markings with service documentation or the existing harness removed from the car.
