uC Control of the ADAU 1702 Eval board

I've been troubleshooting this eval board using the EVAL-ADAU1401AEBZ evaluation board manual and have come up with a couple unanswered questions when attempting to boot the board using a microcontroller (arduino uno).  Where do I connect the I2c SDA and SCL pins to the eval board (jumper number and pin) and is there a schematic I haven't found of the jumper pinouts?  Should the power indicator light come on from simply connecting the 6 V supply to J14 or does the board have to successfully boot for them to come on? I am able to program over USB (the power LEDs lights up immediately upon connection of the USB).

 

From what I gather from page 14 of file UG-072, i2c should connect through header j8 on pins 1 (SCL) and 3 (SDA) is this correct?
