This is actually a pic of an S5 NA ACV, but it's very close to the same. You won't have the rubber hose in the pic, which goes to the 6PI system. And the split air opening has a block-off on it (routes through the LIM). From this thread if you want the explanation: https://www.rx7club.com/new-member-rx-7-technical-256/cat-air-pump-schematic-940050/

Unhook what? An ACV? Search titles for "emissions removal". If the air pump is gone, the ACV inlet can be capped.

off topic, but the FD ACV design is definitely better...
