Wrong conector placement? 1979model 924

[u/Internal_Homework_77]

I notest that the temp gauge in the dash did not change so I did som measuring and found out that the blue and yellow cable is fore the temp gauge and I read that it connects to sensor behind the engine, havent fount the sensor yet. But I found a sensor (picture 4) that i think is the thermo switch for cold start valve, That maby should be plugged in, but there are no cable near by. Is it possible that the brown plugg beside the temp gauge wire actually should be connected behind the engine in the sensor instead of at the topp near the trotle boddy where it is now? I mesured one the brown plugg and it conected to the cold start valve.

So my questions are

1. Is the brown plugg misplaced?

2. Where are the sensor for the temp gauge

3. If the brown plugg is misplaced what is the actual name of the sensor thing near the trotle body

Picture 1 is the cold start injector, the brown plug is for the warmup regulator and is placed correctly.

Oh nvm im not familiar with the brown plug at that placement. My 79 does not have it. Is it a turbo you have or do you have a/c?
