Pulling motor .. few questions

I traded my 00 GT rolling chassis for a stock 90 LX and im pulling the motor to put in a 347 in thats being built by Rick (RNH) now. I wanna yank the ac and emissions bs because its not going to be a daily driver just a weekend beater and have a couple things im not positive about and didnt want to just go rippin stuff out lol.

First thing I think is cruise control related but could be way off, its inbetween the strut tower and radiator on the pass. side..

This 90% sure is emission related and shouldnt need just wanted to double check, its on the pass. strut tower between it and the firewall...

Last is on the back of the upper intake manifold, they have two big connectors, this not sure what it is, assuming that its also emission related..

Any input would be cool.

Thanks for the response .. I know keeping the emissions stuff wont hurt anything or hurt performance I was just going to remove it to clean things up a bit and since will pretty much only be weekend fun I figured screw it lol .. yeaaa I was kinda thinkin going carb but then I jumped the gun and just went ahead and ordered everything and got the ball rollin so ill run this set up for a while
