Screw In Motion Sensor Switch

Hello I have a basement with a 3-way switch in the upper part (a switch) and a foot switch (switch 2). I wanted to replace the switch 2 with a motion sensor switch because we are very bad to leave the basement lights, but I'm having some problems. To pass the one that I have a Black "Hot Line" linked to the town, Panel A (red) below, Panel B (white) on the opposite side.

At switch ON, I am responsible (Black) Trav (red) and Trav B (white).
Step 3: [1-2 to remove power from the box and identify Travis)
Here is the part of the record I think I'm screwed
"Replace the son of the common terminal and a terminal of the switch with short jumpers. [A small piece of yellow wire included] Connect the two riders "Hot Line" and "Trav A" with the connector. Screw the connector clockwise. "
The next step is straight foward
4. Connect the Red son as follows (the new switch) to load (black switch 2) A Trav To Black (new switch) and Trav B in yellow (the new switch)

u need a special switch to do this .. regular motion switch does not work. sorry.
