on the right side wiring harness, there is a wire and connecter after the connector to the cam sensor, need to find where this last connecter goes

on the front bottom of pass. side cylinder head is the cam sensor and connecter, from there, there is another longer wire with connecter. does this go across, under the crank pulley....to where? putting engine back together after head job, and I cant remember...(yes i know i shoulda wrote it down) where this last connecter goes...I'm hoping its important enough to keep the engine from running.....maybe.... Thanks for any help!
