kinda stumped on this one. i keep reading threads about getting the stock f bod cluster to read right and nothing really on what i need to know.

here's the deal. my motor is a 00 with a 98 ecu and harness on it. the temp sensor got smashed so needs replacing. however the 98 temp sensor is a bitch to find in stock as well as the plug for it. i can source out the parts but im curious to know if i can swap to a more common and cheaper 99 temp sensor without changing ecu's or anything like that. all im wanting to do is have the ecu able to read what temp the motor is at so it can do its thing. i dont need any read outs to a guage or anything since i already have one tapped and wired on the pass head.

Yes, you can swap to the 2 wire sensor. Just cut off the 3 wire connector on your harness, forget about the green wire, and put on the 2 wire connector with the yellow wire and black wire and you're all set.

The green wire was only for the gauge in the 98 cluster, so if you don't need that, switching to the 99-up sensor will work perfect.

If I wanted to get my temp gauge working could I use a 98' sensor and hook that green wire up to my gauge wire? Just wondering if it would work.

Yes that'll work. I don't know if the scaling would be exact for your gauge, but late model GM stuff is all fairly close.
