Originally posted by RallyEclipse98 I know the fan switch wire is plugged into the sending unit. You're not talking about that one are you?
No. We're talking about the single wire just below the coolant temp sensor where the waterneck and thermostat area is. That single black wire is what sends the signal to the water temperature needle gauge.
All you need to do is go look see if you see that wire unplugged and plug it back in.
