Default Plug next to speedo head.

G'day 1981 C3.
Would someone please tell me what the plug in question is for.
Have one wire off. Does it have to be working? What is it for?
Thanks Mike

I believe that one is the Vehicle Speed Sensor for your computer command control. It tells the ECM how fast you're going.
