Where is this sending unit?

89' f-150 with 300 I-6. I am trying to find the sending unit that controls the temp. gauge. I have had several different answers. Some say it only has one that controls both the computer and the gauge. Others say it's on the drivers side of the block, and others say the passenger side. Can anyone tell me where this is?

UNDER HOOD, CENTER, FRONT ENGINE AREA, MOUNTED IN TOP
OF WATER OUTLET

It is a one wire sending unit, separate from the water temperature sensor for the computer. I'm not familiar enough with the 300 to tell you where it is, though.

Ok, there are two sending units. One is for the computer, and the other is for the gauge. The one for the computer is front and center. The one for the gauge is on the passenger side at the rear of the block under the exhaust manifold. Most easily reached by pulling the starter.

Thanks. I know that there is one at the front top of the engine near the thermostat with two wires on it. I will go out and check for the other one around the starter.
