I would like to change the instrument panel in my 97 e 320 and want to make sure that after removing the old panel if there is anything I need to consider other than re-attaching connectors. I've checked the DIY for the removal of the panel and saw the cluster replacement and chose to replace the whole panel. I know that I shouldn't have the key in the ignition but other than that what else should I be aware of. Thanks for any help!
