Default Vacuum hose missing??? Pic inside

Am I missing a vacuum hose on my throttle body? See pic- Almost dead center in the pic, above the coolant hose and below the split loom tubing with the pink wire. Is there supposed to be a hose there? If so where does it go? Thanks for any and all info!

Jim

I think that is where the coolant used to run through the TB. It looks like someone did the coolant bypass. I may be wrong. One of the gurus will chime in shortly.
