There is a vacuum hose at the front of the intake above the Idle Air Control Valve, that has been dangling under the MAP that is not attached to anything. My question is where does this hose get plugged into?

 

There should be a vacuum diagram label underneath your hood, if that helps.

 

There is but it is not shown. The diagram shows the vacuum line next to the one I am asking about.

 

Do you hear any suction? If so just screw in a screw and then zip tie it. I was thinking it went to the port just above the arrow, where the blue hose goes. Its been awhile since I had the V8.

 

lol, where is the other end of it coming from? that might help us out some.

 

Should go to the power steering pump line right off the banjo fitting. There's also a second one that goes to the intake tube

 

Thanks Ash, I'll take a look.

 

what hoses are those? Heard the sc300 hose kit wont fit the 1uz

 

Since the SC300's 2JZ-GE is a completely different engine design than the SC400's 1UZ-FE there will be a LOT of differences in where all the vacuum lines go. If you're referring to the vacuum hose diameters themselves usually you can replace *most* of the old OEM vacuum hoses on both engines with a spool of Gates #27042 vacuum hose and cut them all to size. In some places on both engines there will be some vacuum hoses of a different inner-diameter not like the 5/32nds of the Gates #27042 hose.
