MPU-9150 connection to arduino

I found the code for MPU-9150 + arduino here: Arduino Playground - MPU-9150
But I can't figure out how to connect the MPU-9150 to my arduino mega.
I found the SCL, and SDA pins but what are the other pins for and do I need them? ( EDA, ECL, ADO, INT)

Here the MPU-9150 datasheet: http://www.invensense.com/mems/gyro/documents/PS-MPU-9150A-00v4_3.pdf
Sorry, I am a noob so this datasheet didn't make me a lot smarter.

Any help would be greatly appreciated :slight_smile:

I just used the code for the MPU6050 from here: http://playground.arduino.cc/Main/MPU-6050
Somehow it is working with this one. But obvously I canโ€™t use the compass funktion now. Also I am still only useing SDA and SCL and I canโ€™t figure out what the other pins are for.
