Line sensor 2 and 4

Hi Is there a connection diagram to connect sensors 2 and 4? I was looking at the pin out but there is not much information.

I have a Zumo 32u4 OLED version


You can configure the Zumo 32U4 Front Sensor Array to use line sensor 2 and 4 instead of the left and right IR proximity sensors by removing it from the Zumo and moving the blue shorting blocks. When you’re done, one shorting block should be between the pins labeled “4” and “DN4”, and the other should be between the pins labeled “20” and “DN2”, which should look like this:

Please note that the labeling for the pins is on the silkscreen on the other side of the board.
