Don't know. I got one of the 1st kits with the plug-in harnesses. The sensors and harnesses came in seperate packages. Don't think it matters which way they are shipped.
Maybe Tom and the folks at CED are just test fitting them before shipping.

Yup that's normal
I asked crate engine depot the same thing.
They said they connect the sensors at their shop
So when are ya going in for the install?
Try to meet with the tech and go over the fact that
This is a pre made kit.
I wrote on the instruction sheets and put a sticky note on the dash saying DO NOT CUT ANY WIRES
Also be I would tell them and highlight that they must grind off the edge of the lower sensor or it will not seat properly.
Good luck and get ready for the extra power and fun

Just remembered you have an automatic look back in previous posts for a picture to bring in and ask them to make a bracket to pull the lower cold air charge pipe away from engine.
My dealer did a great jobon this.
Not much clearance there.

once again thank you fireman and bigjacks for your help. Yes I printed out some pics to help out the tech and yes I'm going to make sure I talk with the tech and go over everything just in case. As for when I'm getting the install it will probably have to wait another 2 or 3 weeks. The dealer was booked until this Thursday but I'm going out of town and then the week after that I have jury duty in downtown Los Angeles YAY!!!!! 
........so yeah probably 3 weeks but once I'm good to go ill post again and let you guys know how it all went. I really appriciate all the input and advice. I've learned a lot from all of you. Many thanks

Came across these videos on you tube which show some boost issues
related to the GMTU GM turbo Upgrade
the first two videos show boost problems
the last video that the same person posted shows good boost
but note in his video comments he states that it was intemittent as far as getting the proper boost.
Video 1 low boost
video two boost dropping
Video 3 Good boost holding
