I received an inquiry from a customer who needed to know the pinout of the MadCatz TE2 fightstick for PS4. I took these shots to answer his question, and thought it worthwhile to share for others who may want to know.
Here is the pinout of main controller connection. This attaches to the punch and kick buttons.
Once the plastic top is removed, you can see various connections for the joystick, option buttons, and control panel.
