Wiring Talon SRX PID w/ Beam Break Sensor

[DaveL]

I'm trying to help my team figure out how to wire an Adafruit 3mm beam break sensor to a Talon SRX motor controller to control a flywheel shooter.
The SRX is connected to the RIO via CAN.

I've looked thru a number of posts, but have not seen the details of which wire goes to what pin.

We currently are able to pass the sensor signal to the RoboRIO and calculate an RPM.
Now we want to send the sensor signal directly to the SRX and use its processor to generate the feedback signal to the motor.

From Adafruit:
For the receiver, connect red and black for power and then the yellow wire to the digital input.

From Talon SRX Use Guide:
The data port has the following pins:
1) +3.3V
2) +5V
3) Analog Input
4) Forward Limit
5) Quadrature B
7) Quadrature A
8) Reverse Limit
9) Quadrature Index

Should we connect the Yellow sensor wire to Pin 3 Analog input or to one of the Quadrature pins?
