I think these are the temp sensors

Here's what I got:
TVV - 25820-13020
ECT sensor - 89422-35010 (needs washer - 904301-2005)
ECT cut switch - 88790-60050
ECT sender gauge - 83420-16040

Our part numbers are the same except for the ECT sensor, mine is 89422-35010 vs yours is 89429-34010. I checked both for compatibility to my truck which is a 97 and double checked with my vin. Both sensors are compatible with mine. So now the question is, are they interchangeable or they are on 2 different locations and both are needed?

Looks like 89422-35010 is the correct one. Basing off otramm's video, it looks very similar. Looking closely at the diagrams, 89429-34010 seems to be a temp sensor in the transmission. Please correct me if I am wrong. Thanks.
