unknown sensor

I have a 94 yukon with the 350 and 4x4, there is a plug on the drivers side head in between the sparkplugs, does anyone know what it is?

I think that is a coolant temp sensor. (I think..)

Single wire sensor between plugs 1 and 3.
Temp sending unit for the guage.

So its not the same as the temp plug that goes into the intake?

The plug in the intake is for your oil pressure gauge.

No it's not, that goes directly into the block.

No, there is one for the ECM, which is usually up by the water outlet in the intake, and there is one in the head for the gauge.
