Transmission Vacuum Line Help!

I have a 66 gto convertible with a 389 2 speed transmission. I just got the car and found out that the transmission vacuum line is been hacked. I'm not sure how or where it goes other than it connects to the transmission and somewhere on the four barrel carburetor. I just picked up what I thought was the correct line from Ames idea how this is to work, the bends look all wrong. If anyone has an info please help...If you have pictures please send them. I'm lost. thanks

it just plugs into a manifold vacuum port. Most likely it is plugged now so look for it. The tube should end up close to it if connected correctly to the modulator valve.
