There are 4 wires coming from my touch screen:
1 - right of panel (X2)
2 - left of panel (X1)
3 - bottom of panel (Y2)
4 - top of panel (Y1)
I am not sure if 4 or 5 wires is referring to the numbers of output pins (as listed above) or the number of wires internal to the resistive touch screen. If you take a look at page 1 of the following link there is a four-wire and a five-wire diagram both having a 4 wire output.

If both cases (4-wire and 5-wire) have a 4 wire output how can I determine how the touch screen was designed? The datasheet and support for the screen is horrible!
Thanks for the info!
