How do I set up I2C connection? Need help!

Trying to use MSP430G2553 with SRF02 ultrasonic range finder. The code I'm using below is taken from an example on the internet (I'm assuming it works). However, how do I set up the SDA SCL lines?

I was playing around with #define SDA BIT0 and CSL_init(), which is from the grace example in CCS. Don't think those make sense, Please help.

Here is the related technical specifications of the ultrasound: http://www.robot-electronics.co.uk/htm/srf02techI2C.htm

Code:

void main(void) // taken from example on internet
{
int i;
short range[17];
while(1)
{
i2c_start(); //initiate start condition
i2c_write(0xE0); //device address
i2c_write(0x00); //register address
i2c_write(0x50); //set units to inches
i2c_stop();

delay_ms(105); //wait for returning ping

i2c_start(); //initiate a new start condition
i2c_write(0xE0); //device address
i2c_write(0x02); //address of high byte register
i2c_start();
i2c_write(0xE1); //device address but read
for (i=0;i<17;i++)
{
range[i] = i2c_read(1); //read first byte and shift left
range[i] = range[i] << 8;
if(i<16)
range[i] += i2c_read(1); //read second byte and add to 1st
else{
range[i] += i2c_read(0);}
}
i2c_stop();
for (i=0;i<17;i++)
printf("range in inches = %lu\n\r", range[i]);
delay_ms(1000);
}
}
