UPPER speedo cable for 1976 to 86 era GM US Cars with cruise control.
Originally if you had cruise as an option.. you also had then this Transducer.
.somewhere in the engine bay.. the lower cable from the gearbox would go to the transducer.. and then out of the transducer another shorter cable went to the speedo.
This is the latter cable..approx 41 inches long if that makes more sense to some.
It is the cable and casing..
It is the UPPER cable for cruise control fitted GM cars.
It has a screw on thread for the transducer and a push/clip for the speedo.
