help identify hose

[dash05]

I got my engine back in and I'm putting together all connectors and hoses. I got most of them figured out except one. It's located under the throttle body at the back driver side. tiny metal pipe coming down from the throttle body. I'm not sure what hose connects to it. anybody have an idea? I tried taking pictures but not having any luck.

Sounds like throttle body coolant line.. look at the throttle body coolant bypass mod and see if that's it.

Yes that's its! Do you have any pictures of the bypass? Seems every tread or post ate old so some of the pictures aren't working.
