How do you wire a deck in 1992 Mercedes?

To wire a deck in a 1992 Mercedes, first disconnect the battery to ensure safety. Remove the factory radio by unscrewing any brackets and pulling it out gently. Connect the new deck's wiring harness to the car's wiring using a harness adapter if available, matching colors (e.g., red for power, black for ground). Finally, secure the deck in the dash, reconnect the battery, and test the audio system before finalizing the installation.
