MAP hose came loose off throttle body side

I have a 05 and was changing spark plugs and noticed one of the map hoses loose it’s connected to the junction just can’t figure out where it connects to the throttle body at it is the one circled that runs under the air box

Looks like the one that runs to a nipple on the rear most/ #3 cylinder throttle body.
