1996 Jaguar XJR Super Charged Vacuum hose
#1
#2
It connects to the throttle body supercharger adapter assembly

It is hard to tell from the drawing, but the small hose in your photo (plugged with a bolt it appears) connects to a nipple at the top of the throttle body supercharger adapter assembly (item 1 in the diagram). The nipple can't be seen in the drawing, but it is behind that "hump" on the top of the assembly.
This is part of the crankcase ventilation system, and unfortunately ingests a large amount of oil during part/closed throttle conditions, and dumps it right behind the throttle body butterfly, coating it all with oil. This causes the inevitable sticky throttle condition that requires occasional (every few years) cleaning which is a royal PITA on the SC cars (I'm doing it now).
Some people have chosen to just plug that hose as yours is to avoid re-oiling the TB, reportedly with no ill effects. I'm considering the same. I'm definitely installing an oil separator catch can regardless though.
P.S.
It's the broken sledge hammer lodged near the supercharger that has me worried!
