1997 Civic DX Hatch
correct but backwards i think.Looks like a manual trans Y8 intake manifold. They had the 3 wire IACV on the throttle body. Doesn't work with obd0/obd1 though. You can run it without the IACV (it will high idle) or you can bore out the ports for the IACV on the back. Or get one off of an automatic car. They have the IACV on the manifold.
auto Y8s used 3 wire iacv on the throttle body like the Y7s.
Manual Y8s use the 2 wire on the manifold.
