S14 random wiring question

[skazat]

Im doing an rb swap on my s14 and have a connector that Im not sure where it goes or if Ill need it. It comes off of another part of the harness that clips into what I believe is the AC dryer (the little aluminum canister towards the front passenger side of the engine bay) anyways heres a picture of it. Ive looked in the FSM and cant find where it goes.
