The connections can be seen in:
the video (I say where, and show where)
the source code (in the main section of the code)
for example, if you see:
scan_thresh=a2dConvert8bit(3);//sensor reading
that means it connects to the 3rd ADC, or ADC3, which in the pinout is PC3 or pin 26
from memory I think I used PD2 for the 3rd servo, but check the code just in case
