Looks good to me.

Also, if you have to take the intake off in the future: the UIM/Dynamic Chamber/Throttle body will all come off as one piece ^_^ [I have a picture guide on how to do it if you search..]

Not really.

The second jpg? Goes to the double throttle diaphram via a plastic delay valve.

I've problems with the first jpg but let someone else pipe in and give it a go.

I see nothing wrong. In the 1st picture, all 3 of those are vacuum sources, so you can't go wrong. One does need to connect to the thermovalve in pic 2.

In the 2nd picture, the thermovalve will open to allow air to flow between the two sides. Vacuum is applied through the thermovalve and through the delay valve pictured.

On a related note, be sure your double throttle diaphragm works. If you have a vacuum pump, see if the arm moves. I could never find one that did, so I just removed it, the delay valve, and all associated vacuum line. The thermovalve can be unscrewed too.

I was wrong. Didn't pay attention to both pictures.
