So i opened my hood today to check oil and found a wire dangling from the sensor on the fron of the head in the far right corner right up front which sensor is this and can i get a nother one its part of the harness, so i am unsure of what to do.

Sounds like you are describing the Oil Pressure sender. Is your oil light on?
IIRC [And I haven't owned a 5S in years] it just requires a female spade type connector available at any Walmart.
Take a pic - that would help.

Oh well oddly enough i dont have any error lights on thats why i was confused because i would have thought it would have kicked something i will get a pic if i can find my camera.

the oil light will not come on if the wire is broken.
D is right, sounds like the oil pressure sensor.

they tend to get brittle over the years from the heat off the exhaust manifold.
easy fix.
grab a plug and pigtail either used from a junkyard, or from pheonixtuning, or thru art (lagos) here on the board.
cut back the factory wiring to where its not brittle anymore, and splice it in, bing bam boom, done.
