AUX(n) pins and BRD_PWM_COUNT param

ArduCopter Copter 4.4

hello everyone
I’m using CUAV X7+ controller and want to connect lidar lite v3 to the controller using pwm.
according to this video from youtube (link: https://www.youtube.com/watch?v=7K7WGpF2H3g), I should connect yellow and black together with a 1k ohm resistor and connect them to aux5. but which pin is aux5 in X7+ controller? Its pwm pins are labeled from m1 to m14. which one is aux5?
and on the video, the BRD_PWM_COUNT was set to 4. but I don’t have this parameter in mission planner. is it important to set? without setting this parameter, my lidar does not work?

The typical problem with Youtube videos, they are often out of date. Always go to the Ardupilot documentation 1st.
