I believe it helps idle the engine up when the A/C is turned on. Someone correct me if I'm wrong.

If you didn't have it plugged in and you didn't have A/C, I wouldn't think you would be able to notice it. AAC is probably fairly universal among nissans so shouldn't be hard to source if you want a new one.

the A/C one is the FICD with the purple plug i think on the 25.

the AAC controls the idle at all times.. motor will probably idle hunt a lot without it. either that or you would need to idle really high

You are correct sir, purple plug is for A/C idle up. Brown is AAC. Something you definitely want working.
