Re: Wiring diagram of instrument cluster
Without a wire on 5, the temperature light would not be able to come on. In order for that light to come on, it looks like pin 5 would need a ground connection, likely through the temperature sensor. With a temperature gauge, I guess they just didn't wire the idiot light up, but the lamp and housing are still there.
Interesting
