I did this for my bike computer -
http://digistump.com/board/index.php/topic,1938.0.html - not the identical TFT screen but almost the same, and may use the same pinout.
I used the TFT library that's part of the Arduino IDE. See File > Examples > TFT. Pin definitions I used:
#define cs 9 //pin definitions for TFT screen
#define dc 6
#define rst 7but you could or even may need to hook it up differently. Check the data sheet/schematics to make sure you make the right connections - MISO to MISO, SCK to SCK, MOSI to MOSI, GND to GND, BL and +5V to 5V VCC, and LCD DS, LCD D/C, and Reset to whichever pins you defined above.
Hope this helps. Good luck
