Piggyback System X-45

[TN X-45]

Just bought a piggy back system for my 2008 X-45 from wakemakers. Bought a 750 for the port rear locker and a 450 for the port cooler that is plumbed into the starboard side. Thought that was pretty creative of wakemakers. Thanks to Spencer! Any do's/dont's for the install from others that have put this in?
