Alright guys, someone tell me what these two sensors/sending units are?

They are located at the front left of the engine on the front bypass tube.

I beat them up pretty good removing and reinstalling my intake manifold.

Now, my temperature gauge on the dash does not work.

I believe they are both water temp sensors. The one for the gauge being part 83420-20040. The other to support the fuel injection circuit (determines where engine is in cold to hot cycle) part number varies by year but I think 98-2000 is 89422-20010
