Trans won't shift into 3rd, vacuum routed wrong

I know that my vacuum is routed wrong. I did away with the EGR, and have done something wrong. Yesterday I drove it and it shifted harder than normal. Today, it doesn't want to shift into 3rd.

Could I have screwed up the modualator yesterday.

Is there a schematic on the vacuum lines somewhere?

Connect the vacuum modulator to a manifold vacuum source. Make sure it didn't get knocked off the transmission end to.

OK, I'll re route, but I have ask this question twice and no one has responded................there are two metal lines that come up the firewall at the back of the engine. One crooks toward the left, one crooks toward the right in a cane fashion. Which goes to the mod. and where does the other go. The truck does not have power brakes so it isn't a booster.

Surely mine isn't the only one with these two lines.
