Yes. The IAC does not mount to the throttle body. The air bleed hose attaches to the side of the throttle body and then runs to the back of the manifold where the IAC mounts. I have the IAC in hand so I knew what the part looked like. I just couldn't see its mounting location due to how my engine sets back under my swim platform. Thanks all!

I have same issue but cannot find port to install air bleed hose. Is it directly below IAC valve?
