FiOS isn't a self-install kind of service. What exactly did you order?

"All knowledge is worth having."
Something's definitely wrong then ... for a FiOS install at a new location they're going to have to come out and run a FiOS fiber optic cable from the side of your home to the location where your neighbor's cable ran to -- and dig up the yard again the process most likely -- and then install an ONT (optical network terminal) and power supply and then connect it up to your in home wiring (cable, phone, etc.)
FiOS initial installs are not "self-install".
Subsequent DVR/STB installs in a home that already has FiOS are self-install, but that's about it.
