'89 F250 5.8 Temp Guage not working
I just bought an 89 F250 with a 5.8 liter. The truck runs strong, but I noticed that the temperature guage doesn't work. I replaced the sensor (the one with a 2 wire connection near where the hoses enter engine) and still nothing. When I was searching for a part number online for that sensor before I bought it, I notices that there were two listed on most sites- one with two wires (the one I bought) and another with just one (green) winre connection. As I was replacing the one I get, I noticed another sensor with just one green connection.
Is the second a coolant sensor as well and if so, could that be the problem?
Thanks!

For a few bucks more you could have put a real temp gauge in. The stock one on my truck technically worked, but was more of an idiot light. It would rise to a normal spot, and never move at all. It took me a while to realize that my thermostat was stuck wide open, since the gauge didn't reflect that.
For $20 I put a mechanical capillary tube gauge in, that actually tells you the temperature instead of "normal". Ford gauges suck.
