Search previous threads & read that on older generation E series, we can switch fuse # 53 & 54 to their second position in the fuse box in the engine to change all 3 power plugs from temp on to always on, even after engines is off for a while.

Does anyone know the exact which fuse box (the one in engine or one in trunk) & which fuse # to switch to have always on plugs in our 2015 E400?

Thanks,

Ask konigstiger, I am sure he may know.

 

Thanks for the links, but the first 2 applies to 2004 & 2005 models, & I already have printed out the last one's diagrams, but it doesn't apply to my 2015 E400 or a quick instructions to move fuse #xx from position 1 to position 2, etc...

& looking down the long list, is it called "cigar lighter" or "plug" or "socket", etc...

 

Search x58 in rear SAM attachment, no option to move fuse(s).
