I'm assuming the yellow pneumatic lines coming from the CLP attach to it. I have never seen that box anywhere, but I can tell where I haven't seen those yellow lines - behind the instrument cluster, or under the steering wheel, or behind the center console (could be behind the heater box, but I've never removed that), or in the inner passenger amplifier area under the passenger side carpet. I have seen the yellow lines running along the interior driver's side rocker panel, on the passenger's side of the trunk, and to the locking mechanism in the lower center console. Maybe that helps a little.
