I know its a Corvette because you have Aluminum Cylinder heads.
Only Corvettes had Aluminum heads in that era or time frame.
If an L-98, thats the coolant temp sensor for the dashboard coolant temperature gauge.

Hi
It may be the coolant sensor for the aux fan, if it is the same as my 89, the dash sensor is on the other cylinder bank between 6 and 8
To check earth the wire with the ign on, if it is for the aux fan the fan will run if it is for the coolant sensor the dash gauge will go to max

'90 + have dual fans on rear , both controlled by the ECM
In '90+ L98's , the hole in question had a blank plug with a square head
It is the correct type unit for the gauge ; just in the wrong location for your year model.
Maybe the heads have been off and they couldn't be bothered to remove the plug to swap over
Does wiring to it appear stock ?
What have you got in the same hole on pass side head between # 6 and 8 cyl ?

I remember the dash coolant temp gauge wire on my 87 being a 16 gauge GREEN wire.

Some people should really leave the keyboard alone and not take wild guesses or at least wait until the medication has worn off
Sensor shown in post #1 looks nothing like a knock sensor
If fact ; with the single blade terminal it doesn't even look like the factory Aux fan switch
which has same style connector as the knock sensor

Have a look at your block , Pass side ,in front of starter and see if something like this is there
A KNOCK SENSOR

Exactly
OP stated his was a '91
Very little about your '84 CFI engine is the same as a '91 TPI engine except for Chevy on the rocker covers
and the dist at rear
Who told you, your unit is a knock sensor?
Yours would be the only '84 with a knock sensor in the drv side head where every other '84 has the gauge sender unit?
No .
I correct people that put up miss-informed , bad or plain out wrong info.
Just because YOUR year model has something , doesn't mean another year does
Even worse when you make a blanket statement like you did that is wrong for ALL years`
Post up a pic of your knock sensor in your head to see if others agree with your opinion
