What is a specific wiring harness?

A vehicle-specific wiring harness is tailor-made for the type of vehicle in question. They are characterised by the following benefits:

Compact plugs can be directly connected to the vehicle-specific plug connector of the rear lights or defined hub points. Installation time is considerably reduced and connection errors can be ruled out.
Control modules, sockets and grommets in a vehicle-specific wiring harness are aligned exactly to the electrical system and the vehicle geometry. The length and layout of the leads is designed to fit perfectly. This facilitates fast installation and flawless functionality.
The complete installation material supplied allows for proper installation and has been designed specially for that type of vehicle.
The installation instructions describe the installation and all necessary steps clearly in the form of text or images.
