Yaris 1sz fe - electrical questions

Hi all,

New here, I have a Yaris mk1 1.0 race car - firstly I have replaced the ECU and engine loom in the car can anyone tell me what the blue plug is for in the attached pic mounted on the side of the air box? Coolant sensor or similar? Secondly it is only the engine loom and ECU that is in the car as the rest is not needed, can anyone tell me how I would wire rhe OBD reader directly into the ECU? It's a French build ECU and loom - all the wiring diagrams I have are for the Jap built versions. Any help is hugely appreciated.

Thanks,
