I took off the UIM and ACV to remove injectors and was pretty good about labelling each hose that I disconnected. But in the picture there is a lone tube (circled in yellow) that was either not connected to anything in the first place, or I knocked off the label. I dont remember labeling that one though. Does anyone know where it connects to??? Thanks

 

Throttle body coolant hose. There is one on the top back side of the TB as well. It may have had the TB coolant mod done to it. In which case it is no longer in use.

 

its the coolant hose that attaches to bottom of throttle body

 

the water coolant hose from the uim should be hook to that one.do you remember now?i hope it would help you out

awesome thanks for the help! I remember that hose now, I had to cut it off when removing the throttle body and didnt label where it connected to.
