Right, I hear ya. That stuff they do screw up from model year to model year... but my Mustang... they went from a speed density EEC starting in 86 and changed that to a Mass Air setup, the harness and everything was identical with the exception of a few wires... the pinout was slightly different and in some cases (depending on the non MAF car) a couple of wires needed to be added. Anyway, they have both versions in the back of that manual... I would assume it would be the same for the Contour.
