sorry about the angle of the picture, if you tilt your head to the right its the right way

red circle is return line from cooler for trans oil,

Modulator with dual vacuum lines: one line(center) is main manifold vacuum... outer vacuum line would be hooked to ported vacuum source.

The two lines work together for controlling shifts. Ported vacuum would help the trans to down shift sooner in a situation like turns the vehicle did not stop fully at.
