Coolant Temp Sensor Location?

Coolant Temp Sensor Location?
I have a 1999 Ram 2500 with V10 and was wanting to check the coolant temp sensor because of some hesitation and stumbling on acceleration when the engine is not warmed up yet. I looked in my manual and the picture of the location does not show what I see under my hood. Am I overlooking something or does anybody know of a misprint on this. I see the temp sending unit with the two wires coming off of it for the gauge function and there is a spot next to it in the thermostat housing that looks like it was meant to have the coolant temp sensor drilled into it (matching where my manual says it should be) but nothing is there. Any help? thanks

If the v10 is close to the same as the v8, the one you could see is the only temp sensor. I think in later 97 or early 98 dodge switched to a single sensor, which runs the computer which tell the dash what to say.
2 wire sensor goes to the computer, single wire sensor goes to the dash, if you have 2 sensors..

I'm wondering if you would know, if my truck does have the one unit that does both functions, and the dash light and gauge "part" of the unit is functioning correct, would that mean the engine function from the sensor would be working correctly too? Or can it be that the readings between the two are not necessarily in synch?

As far as I know, they will be in sync unless the computer is dying. There is an air temp sensor on the right side of the intake (it pokes into one of the runners) that can cause some goofy fuel stuff to happen. You might see if you can find a way to test it, or plug a scanner into the truck and see what it says. This way will also tell you the water temp the computer is seeing. I don't want to send you buying parts that might not need to be messed with.
