Speedo way off...!

I always thought those were cruise control speed sensors.
A ratio adapter wouldn't need a wire for anything, but a cruise control does.
The Wife's 72 Swinger has one that's coming off because we have a new cable for it.

Does the one on your wife's Swinger look like the one in the picture I posted? I have searched for anything that looks like this and cannot find.
