I tried to figure that out yesterday too. I think it's the Connect+ toilets, but the website only shows them WITH the washlets, not separately. The photos don't seem to show the hole at all, plus they've photoshopped the power cord and water line out entirely. They should be at the back left of the washlet seat. I don't know how it works in skirted models (or even if the hole is an option), but in the traditional ones the hole doesn't conceal the cords entirely, just lets them go straight down instead of arcing out around the outside of the toilet itself. Here's a photo of ours arcing around the outside with a Toto Aquia (must not have had a Connect+ version). You'd think you could at least get a shorter waterline, but it's pretty well hidden with our bathroom layout so I haven't worried about it. Until now anyway. :)
