Here is what we at Big Fish have come up with for an Xplore and Mega Live 2 on an Ice or Portable shuttle.

Please confirm the shuttle you plan to install on upon purchase - HDi shuttle uses Wago lever nuts, ArcLab shuttle uses spade connectors.

This is one short PC13 with a Fuse holder for the Xplore or Apex, you must match the fuse to your screen or let us know which model it is, and we can include it.  The other power cord is a long PC13 and 10' Ethernet Combo that seems to be the perfect length for an ice bundle, we then cover that in flexible sleeving like used when rigging boats.

Connect those two cables to the Mega Live and the Ethernet and Short PC13 to the screen and you are in business!
