Wiring the IR Receiver

I know this has been discussed before, but I am curious about the voltage requirements of the IR Receiver. The documentation states that it requires between 7 and 15 volts of power. For the sake of reducing wiring and the use of expensive PWM cables, I proposed that the entire board be powered off of two pwm cables. Basically we would have one cable sitting sideways across Digital Inputs 14 - 16. It would cover all of the signal pins on these Digital Inputs. The second cable would be on Digital Input 17. This would have the ground, +5V, and Signal. The ground would be connected to the ground, the +5V would be connected to the power. The 4 other wires would each be connected to a signal pin.

I have tested the IR sensor with my bench top power supply and it was able to operate all the way down to 3.5 Volts.

Does anyone see any problems with setting the sensor up like this? The electrical advisor wants to pull power off a of a PWM, but I am trying to reduce the wiring and keep everything organized.
