I recently purchased a water temp sensor off of summit racing for a 2.8 engine the sensor is located on top of my clynder head rear right but the sensor has 2 small plugs in it and I didn’t know if it will work
This is the location of the 2.8 sensors. The temperature gauge sending unit has a round plastic head with a split in the side of it. The Coolant Temperature Sensor has an oval plastic head. Don't let a parts house convince you that you need to cut and splice in a new harness end. They're trying to sell you the wrong sensor. It commonly happens when someone buys the gauge sending unit that they provide the coolant temperature sensor and a new harness plug. The only sensor with a single wire is the cooling fan switch.
ECT used by ECM w/ old style plug for Fiero V6 and many others hasn't been made for 20+ Years. If you find them they are very NOS parts. Old connector was a big reason of engine problems.
New ones use a Metripak plug and much more weather and idiot proof because of its resistance to spilled coolant that's very conductive. Dorman and others make pigtails to install new plugs. You should solder or otherwise make a very good connection and water proof the joints.

That is the part yes but what confused me was that the temp gauge sensor is what I thought was the coolant temp sensor so if this part is correct then I should be all good thank you for the help
I don't know that I have VigLink. I was using Firefox as my browser. Anyway, I went to summit and entered the part number. The sensor you have is the coolant temperature sensor and isn't the one that screws into the trunk side head near the ignition coil.
I checked again and Summit doesn't list the correct sensor for the temperature gauge. It's usually readily ad your loxal chain auto store.

Do you suspect your ECU is being sent incorrect temp information?
That sensor goes in the end of the engine, underneath the thermostat housing. It doesn't feed any information to your temperature gauge if that's what you're trying to do.
ACDelco Number I posted above is a example of The New Type ECT and will require a New Plug for most Fiero. Only 87-88 Fiero w/ DIS Dukes have them installed at GM. Example new plug Dorman 2-Wire Coolant Temperature Sensor pn 85100 Sensor is none polarize and not connected to case so wiring doesn't matter.

Correct. PFF users don't have a program etc called VigLink. You Browser access X site and X site runs "it."
Very Short version: PFF and Many Others have "Scripts" calling for VigLink.com. (Wiki) Many people use Ad Blocking and other plugins that hates them. Some Browsers can block it too.
By Blocking I include "Security warnings" by a Browser or plugin.
Note that Opting Out of VigLink ( https://www.viglink.com/opt-out/ ) and most others often does not work. If they Honor the Opt Out, (Many do not believe them.) 1. Big issue is you have to do this for every browser on every device you use. PC users often have 2 or more browsers (I use 3 min every day, more sometimes.) then add Phones Tablets etc. 2. If you clear your cookies etc for any reason then often have to Opt Out again because many uses cookies. In this case: cookie name 'vglnk.OptOut.p' is set to 1
PFF uses only a few 3rd party scripts over the years. CNN and Many Many Others runs 20 to 100+ 3rd party scripts and most track you. Is bad enough for many but is a proven nightmare for Security. Several Ad Farms have sold ads w/ malware scripts. Worse problems because many 3rd parties have little to no security at their sites and they often get hacked then DailyMail.co.uk CNN and many others push malware to all w/o hacking them.
thank you guys for the help im currently in the process of removing the old wire harness and adding the needed connectors and swaping the ecm connectors any tips on that? also any break in tips/tricks i dont know if i should turn the engine over with no tune since i will be adding a twin throttle body (home made) cam rockers and possible headers or power logs also home made. and finally i need lifters still for my engine and i was wondering where to get some i have a 260h cam and i was searching for some on summit racing but i didnt know which to get since i have the 2nd gen block with a camaro lower intake manifold and fiero heads.

I have never seen a Fiero harness with anything but the metripack CTS (Coolant Temperature Sensor). Note this is also sometimes called the ECT. This is the sensor that the computer uses to tell the temperature of the engine. The wire will be Black and Yellow. Your Fiero should already have the correct connector on it for the CTS.
If the two wires you are looking at are Dk. Green and Dk. Green/Yellow, then what you are looking at it the Temp Gauge/Temp Light sender. That never uses a plug like shown and will not function with a CTS sender spliced onto it's wires. You need to purchase the correct sender for the gauge and use the original type sender.
There is also a Coolant Fan switch on the engine, but that is a one wire connector.
There is also a Cold Start Temperature Switch on the engine, but that is also a different connector and different colors.

Tim I have been trying to reach you by email, phone, and pm. I saw you posted here so just tried to call you but no answer. Is everything ok?
