Playstation 2 Joystick (totally removed) connecting to Arduino UNO board...etc.

Hello all...
Been working on this for a while now.  I purchased a generic playstation 2 (ps2) gaming pad, hand or controller (your preference).  I completely removed BOTH the joysticks from the unit as the native state of how they were, would not work for the project.  I DO NOT want wireless, and that first off is all I am finding online.
My question is this: WHERE do I connect the SEL (My understanding is this is where the pushbutton operation of the joystick would be wired)
Do I connect the SEL of the breakout board to the actual Arduino, or do I connect it to the breadboard.   To both, just give me a location as in 3 thru 13, A0 through A5,
Now then, I have power, ground, left (left3), right (right3) figured out.
Am I totally off my mark, I have attached my fritzing diagram as a jpg with notes to assist.

For reference purposes please see these links for further info:
Breakout board:

Thanks  in advance

The button portion of the stick is no different than any regular push button (i.e. the button will connect to one of the digital pins). Just a matter of figuring out weather the button needs to go to ground or power. So take out your multi-meter and check continuity between the select, power, and ground. Connect your leads then push the button and see if you get a short between the ground and select or the power and select. Based on which way the button goes you'll need to program the button press accordingly. Be it pulling high or low.
