Vacuum routing to automatic transmission

I'm trying to put together this '87 with A/T and need info as to where on the manifold does the A/T connect to?
I have looked all over for diagrams, but they are all for M/Ts no info about where to connect the vacuum line for the auto tranny.

i would just hook it to a good vacuum source, as all it does is control line pressure, without vacuum, max line pressure!! firmer shifts and wont suck as much.

If that is the case, then they would not have put the vacuum line there in the first place.

I agree, and I'm trying to do the same with my '86. I'm gonna run it down while I'm adjusting my e-brake cable. I'll let you know what I find.
