@Z. Changazi Welcome! Please post a photo of the E300. Can you take your vehicle to the dealer? It is covered under warranty. There is also a paper circuit diagram in one of the fuse boxes. Try looking through your owner's manual. If none of this works, please post your VIN and someone can look up the wiring diagram.
