Hi Guys I am trimming down the wiring harness and keeping the Computer and fuel and starter circuits. The TGV's are gone with the motor and sensors.

Can the PVC diagnosis connector,power steering oil pressure switch,Purge control solenoid,pressure solenoid valve,Drain valve fuel tank sensor control valve and fuel tank pressure sensor all be removed and then programed out of the computer so there are no codes thrown for these issues?
I am in the heavy part of separating the engine/computer harness from the rest of the wiring and it would be easier to cut some of the unused circuits rather then remove the pins from the connectors.
Thanks Don
