    I've got a 1989 4runner, new to me. Maybe put 400 miles on it so far. My temperature gauge doesn't work correct (immediately goes to operating temp when cold crank). So I was looking at which style I need and found this random plug not being used. Everything works well but would like to know what this used to go to. Everything I've checked has a plug attached. The plug just goes into the wiring harness. Thoughts?20230921_165108.jpg
