Default Transmission modulator line on TH400

I was underneath the Vette and noticed that whoever reinstalled the transmission(TH400) did not hook up the transmission modulator line. I will be ordering a replacement, but I need to know how it hooks to the transmission, and where it hooks up to the vacuum source. Can anyone help me figure this out so I know what parts I need to order?

73,
The modulater line goes up from the modulator, passenger side, then attaches to the top vacuum port on the manifold just behind the carburetor with a very short vacuum hose ta a "Y" fitting made to attach two vacuum lines. You can find all the fittings/line in the Zip catalog :thumbs: This should help you....
