Hello, I installed the original car radio today ,and I found two unknown wires in the radio area .I am interested what using they have. On one plug was the following code: 013 545 23 28. All the buttons are functional on the car ,were not taken by me, by mistake.:)
The car is: W202 C280 ( 1994 Year).
