Connecting and Using the On-Board Computer

Model: Peugeot 406 MK 1 - Years 1995-2005
Part: Onboard computer

In the following guide, first remove the wiper and disconnect the plug. Insert the wires for the on-board computer into the missing pins in the wiper socket. Use a bit of wire to connect the two wires, and by connecting them, the on-board computer display changes. The display is shown after changing the mode of the on-board computer, which normally indicates the date, but in this case, it is displaying other information. Once the on-board computer is installed, the most logical step is to obtain a wiper lever using the on-board computer button, but this guide shows a less sensitive option, which involves disconnecting a wire from the back of the plug and demonstrates how to do this. The two wires of the on-board computer have been connected to the cigarette lighter, which can then be used as a button to operate the on-board computer.
