Looks fine to me, Paul. Note that only the European TS-480 version has both control cables
included, which is maybe why the manual indicates otherwise.
Mike may answer you on the wi-fi card, but it is just a drop-in to install, so no need for a factory
install. You have to open it up to do the jumpers, anyway, and that takes less time than a couple
of jumpers to install.
