The hoses for it don't hook up behind the vents. There is a difuser box or vent work behind it that curves to the right and then down, right past the knobs, and into the unit under the dash. I am hooking mine up with Vintage air, so I may fab this portion so that it does hook up to hoses and then I can sell the rest to someone and not waste it. In the end, I'm only using the vent and everything else from Vintage air and their knobs that are really close. Here's someone elses picture of it.
