Hello, about the SuFu I have already found out that for the activation of the pre-set cable 1. the fuse and 2. the component 9442190 is necessary. Unfortunately the mentioned links to the installation instructions of Volvo dead-end lanes, the pages are no longer displayed. So, now the question: What is this for a component and where does it come in? Can you possibly bridge this? On the display by means of the on-board computer it does not matter to me, the connection is only “consciously” used under supervision. I would like to install to the right instead of the cigarette lighter socket two 4mm sockets for my model construction charger and would like to use the pre-installation e.g. fuse and cables. Greeting, Elchisti
