Are you referring to the secondary air pump? they dont connect to the CCV?

Early versions have a hose assembly that fits to each CCV valve on the top of the rocker covers and are joined together and connect to two ports on top and below of the throttle body on the inlet manifold.

Later version use two individual insulated hoses

If your referring to the secondary air pump, the hoses go to two metal valves at the rear of the cylinder heads, they are not called CCV's.
