I have a 2012 e350 w212 with pretty much all options. Nonetheless, having trouble with locating fuse or wire tap that is powered while car is on. I have the Valentine 1 with hardwire kit, an handy when comes to installs but cant find a diagram anywhere. If anyone can help me out with which fuse or power wire i can tap im highly appreciative. I located fuse panel in trunk an have long enough cord to get to windshield, just not sure where to take power from...images or details are a help thanks. If theres a closer fuse panel closer to front windshield that you know of ill listen too that too...
