It measures the air temperature in the cowl and sends the info to a controller that retards the spark under certain conditions.

One part of that NOX package is a speed switch mounted on the trans speedo connection, it provides a ground at 40 MPH....useful for OD conversions and other mods that are speed related.

john, it's hard to tell from the pic [my old eyes], but is that the 7/8"x20 [?] speedometer cable thread on both ends ? what years were those used and do you have a part # ? also, are there other applications in other years and makes that uses a similar part ?
Yep, standard speedo threads at each end. I believe these were used in '71 and '72 only on cars with the NOX reduction package. P/N is 3438494
