2015 AMG SL63 (R231)
Switchable 12V in door

Hi All,

I am trying to find switchable 12v somewhere in the door of my 2015 AMG SL63.

When I am testing cables from the door control module, I can only find permanent 12v. Without the door card connected, I can’t really lock the car and measure from the inside :/

Any idea where to grab switchable 12v or the wire color?

thank you so much in advance.

Do you have a VIN? I can probably post the wiring diagram for the doors from the WIS. You should be careful not to overload certain circuits, depending on what you're hooking up.

Pulled a VIN off Autotrader...
May not be an exact match but, may help.

edit: assumed its for the drivers door.
See attached PDF.
