The offered wiring harness is from a dismantling, meaning it is an original Mercedes component that has already been in use in a vehicle. This type of solution is particularly beneficial for electrical systems where compatibility with factory connectors, wire lengths, and mounting methods are crucial. Original construction promotes seamless integration with the existing system, without the need for modifications or additional connections.
