Wiring a PS2 handle RX to Nano

Ive been building a 3dof hexapod spider robot and i would like to make my project controlled offline with a wireless PS2 handle.

My set up will actually be a pololu maestro 24 channel servo controller and an arduino nano to send signals to the meastro via the PS2 handle.

Ive found some good info including the arduino library to do so and a schematic telling you what wires on the RX do what but i cannot find how i would actually hook up the RX wires to the Nano.

Any info would be appreciated.

Heres a link to the info i found.

Ok i found this diagram on how to hook up the wireless unit to the arduino.

But it says on this page..........

........that i need a pull-up resistor on two wires. Does that mean that they need to be in line with wire? Like wire-resistor-wire.

Ok this is the link to the PSX_lib.h file.........

About halfway down it gives constants for each button. Are these the numbers that will be transmitted to my pololu?
