A mounting assembly for a roller window shade includes a mounting bracket, a motor coupled with a shade tube of the shade, and a wire. The mounting bracket includes a body having a first surface and a second surface and a protrusion fixedly coupled with the body and extending perpendicularly from the second surface. The first surface bears against a flat surface. A passage extends between the first surface and the second surface. The motor defines a recess that receives the protrusion. The wire extends through the passage and couples with the motor. The mounting bracket and the motor obscure the wire from view. The passage extends at least one of proximate and through the protrusion such that the wire extends into the recess when the wire is coupled with the motor and when the recess receives the protrusion.
