The source identifies the illustrated replacement kit for model-year 2022–2024 Mercedes-Benz C-Class W206 vehicles and describes that setup as requiring no programming. Confirm the supplied kit and vehicle configuration before applying the guide. It shows two different wiring arrangements; use the instructions for the supplied harness.
Product and wiring options
The source distinguishes a splice-in parallel harness from a plug-in adapter harness. Their signal-wire arrangements differ.
Installation sequence shown in the source
1. Remove the door panel
2. Remove the associated mirror components
3. Replace the mirror base
The images show the disassembly sequence. Obtain the applicable power-isolation and fastener-tightening instructions for the vehicle and kit before working; the source text does not provide those specifications.
Wiring arrangements
Splice-in parallel harness
For the harness illustrated in the source, red is the supply lead, brown is ground, and yellow is the signal lead. The source shows the module red lead connected to the vehicle red/white lead, and module brown to vehicle brown at the door module’s No. 2 white connector. These are separate supply and ground connections; do not interpret the English image’s wording as connecting the supply to ground. Confirm the exact connector and terminal assignments for the supplied kit.
The module’s yellow signal lead is shown connected to yellow at the left mirror’s No. 4 connector, and to white at the right mirror’s No. 4 connector.
Plug-in adapter harness
The source shows the lamp lead connected to the module’s 2P output and the white adapter plug connected to its 5P input. At the illustrated door module’s No. 4 white connector, the source describes these terminal-wire pairings: left yellow to adapter black, left white to adapter red; right white to adapter black, right yellow to adapter red. The body also mentions green as an alternative to red; confirm the actual supplied harness rather than treating both colors as interchangeable.
The adapter is shown inserted between the door module’s No. 12 connector and the original plug. Connector numbers and photographed orientation belong to the illustrated configuration; they do not establish universal cavity assignments.
Vehicle settings and operation
The illustrated menu path is Settings → Vehicle → Auto-fold mirrors, and Settings → Lights → Interior/Exterior lights → Locator lighting. Check the corresponding settings for the vehicle’s actual interface. The source describes the puddle lights illuminating after the power-folding mirrors operate when the vehicle is unlocked.
Troubleshooting for the illustrated kit
- If neither light illuminates, the source refers to the module input connections, loose or reversed connections, the illustrated vehicle settings and the 5P wire order. Confirm the terminal functions before reconnecting; reversed connections can damage the module.
In the photographed view, the source lists the 5P colors as brown, green, red, black and purple. This view is a color-order reference, not a numbered pinout viewed from both sides.
- If one light does not illuminate, the source suggests comparing the left and right modules and their input/output wiring. Swap modules only where the supplied kit’s instructions confirm they are interchangeable.
- If the two sides behave differently, compare the applicable signal-wire arrangement above against the source image and the supplied harness. Do not mix the splice-in and adapter instructions.
