Re: vacuum hoses

It should be on top of your radiator shroud.

Re: vacuum hoses

The 94 diagram will differ a bit:

- There is no "TO DIST" (Opti vent system vacuum) hose on a 94.

- The PCV vacuum does not come from the port under the throttle body. There is a large "C" shaped hose that doubles back to a port slightly behind the PCV valve.
