Take note of the clocking of the pump compared to your old one, if they are not oriented the same way, you will need to spin the shaft of the pump until they match. The notch is facing down on the pumps in this picture. You can't install it incorrectly, it will not go into place due to the key way on the shaft. On my new pump, I had to spin it 180 degrees
Installation is basically the reverse of removal. Torque all the critical bolts to spec.
After installation, the system needs to be primed in ISTA+. There may be other programs that will do this task as well. Not sure what would happen if you skip this step, but given that air in the pump is one of the potential causes of failure for this pump I wouldn't chance it.
