Sooo...I need to jumper pin 7 to the right resistor and sort out power to pin 6.  Can the power for pin 6 be jumpered off pin 6 on U17?


Provided the pin 6 is meant to be permanently tied to +5V it can be jumpered from anywhere that has +5V permanently including pin 4 or 8 of the same device (assuming these too are permanently tied to +5v).
