Hello, would like to give my new purchase R107 450SL a new dashboard and center tunnel before I allow it. Both components are organized and lie in front of me. Would it like to exchange and install it itself, and not leave such a work to the “MB master of my trust”. Does anyone have an installation and installation instructions for the amp board of a 107er, as pdf or similar, where I could hang along? Thank you very much in advance. MFG Ben
