Installing BHT-2 moisture tester in an inline baler - what is the cut side ?

Baler - MF 1840 inline , I have the pads mounted opposite each other , on the tension rails, top and bottom, instructions say mark the set of wires you have on "cur side " so you can plug into the monitor correctly. But the " cut side" is both top and bottom of the bale on an inline right?? So which is it then ??? I'm confused
