Engine codes !!HELP!!

I took the AC system out today. ALL OF IT. The condenser, compressor and all the lines. I bet I took 15lbs off just with removing the shit. I had to cut a few wires off of the system they were only connected to the AC stuff. Will that make my car show something being wrong (throw codes) or will it be fine unless I turn the ac on?

Well I finally got the guy paid off and I am going to drop the engine in sometime this week. I have 3 days this week to do it. I have to goto school on those three days also. So I have from 3pm to about 11pm to do it. I think that I will be able to. Anyone have any last second tips for me?
I decided to go ahead and do it now since the front was off along with the radiator and the AC shit.

I don't think the engine throws codes for things that don't affect how it runs, and A/C broken or working fine won't make the engine stop running.
