What we did was IC2 and its those 2 sets of 4 pins next to the phone jack looking port. Make sure to use the 4 pins closer to the phone jack. we just used two 2-pin connectors, the ones with female on both sides.
As far as the gyro is concerned, make sure to plug it into the analog breakout, the thing that goes on the module.

dont forget to change the jumper and the analog breakout needs to have the wires going into the PD board.
