The AIR pump can be turned off in the PCM when you pull it out. I wouldn't cut up the wiring harness though. If you REALLY want to drop the extra weight of the extra wires (really - 2lbs?), I'd buy a used harness from somewhere (make sure it's compatible) and cut that one up. Keep the original one in good shape in case you decide to sell in the future.
You can delete anything not used, I do it all the time for engine swaps. It's a good way of eliminating potential problems and make everything look clean.
