The engines are all the same, regardless of the designation of the Exige model. As far as I know the wiring on all 07+ Exige models is also the same, but I can't say for certain.It is part of the wiring that came with the 07 cup255 engine. My car is and 06 exige NA.
His has only two wires (versus 4) and is the wrong color (clear versus black).Check to see if it plugs into an intake air temp sensor; you would not have that on an NA car...........
