The coolant temperature harness is a part of the engine harness. If you follow the wire it will go to the main harness.
So, what is the issue with the connector?
Is it damaged/burnt? Or are you not getting power to the sensor?
If it is a damaged connector, you should be able to get a replacement connector and splice into the harness.
I have attached the wiring schematics for the temperature sensor below.
Please let me know if you have any questions.
