Are they hard to setup?
Nope: similiar to regular sticks except for the 1 ground, and the need for a +5v source (which is available on your ipac, or other places within your cab)
Do i need anything special? (Im getting an IPAC)
besides and ipac, some quick disconnects, som wire, and some know how, no...
Anything else I should know?
I'd do a search for p360's on this board for all you wanted to know about them (including hookup) and more... there's a lot of good info to keep you busy while you wait for the ups truck =P
Good luck, and let us know how they work out in your project.
