Step 6: Retrofit illuminated reflectors (optional)
Focus on the gray rectangular plug with the pink clip. Press the small tab to release the pink clip and pull it upwards. Pull out the plug and cut the bundle that holds the wire harness.
Behind the pins are hidden, where 2 of them will be used to provide current to the reflector lamp. The row has to pull out the white plug, pulling the fuse to the right and lifting the remaining piece.
We take one of VW's cables and cut it in the middle. Then connect each cable of the illuminated reflector to each end of the cable we cut. We use insulating tape and / or adhesive for joints.
Our goal now is to find out which terminals the two reflector cables must connect.
In our car and the driver's door, the terminal of the 1st and 3rd lines was on the ground, while the 1st and 2nd lines related to the current.
You can try to see if they are the same terminals in your own case by putting the red cable on the power terminal and the black on the ground.
If it does not light up, then we follow the following procedure.
The red reflector cable is plugged into the socket that ends in the red-yellow cable and continues to carry power. The black cable is touched on each of the terminals until the reflector lamp illuminates. This is about grounding and we note the position of the terminal when we find it.
You will notice that it may unlock the trunk or open the gasoline cap, which is normal.
Then, keeping the black cable in place of the lead we found, test the red cable on one of the other terminals until the reflector lights up.
Place the corresponding wires in the corresponding positions of the white part and place it in the gray rectangular plug.
Pull the cables with an insulator, put a new bundle and plug the plug back into the driver's seat. If everything has been done properly, the reflector will light up.
What is left, is to to unbutt the old reflector from the wallpaper and lock the illuminated reflector.
