Pin outs were never posted.
Studio XPS 435T is sister to Studio XPS 9000.
Studio XPS 9100 is standalone.
Page 43 shows pin 23 badge back-light connector.

it is a 3 pin keyed header on mobo but the cable has only 2 pin. the design is to prevent wrong orientation of cable connection to header. the 2 pin cable I guess is either +5v/gnd or some other for a white LED. one of the cable is red so that may be the +5v. some one that has 9000/9100 mobo and multimeter can measure it.![]()

I tried again still does not work for me. but thank you for successfully upload the pic I want to but can not. header 23 is light board it has 3 pins keyed. only two of three are used to control light board.
