Remove the blue plastic covering the adhesive on the new cable.

Align the cable so the side marked "KB" is up and toward the bottom of the phone.

Insert the new port where the old one was.

The red gasket seals the connection, so it will be tight.

The cable is keyed to the gray plastic peg highlighted in the second photo.

Make sure the screw holes in the new port align perfectly with the circuit board.

Press the cable down over the plastic peg which will attach the adhesive.

Reconnect the "MB" side of the cable to the highlighted port on the main board.
