Ok guys, this is prolly the beginning of a ton of questions about wiring for you guys. On the drivers side, just to the right of the rear rotors trailing spark plug (just above a coolant hose) there is a sensor with a one wire connector to it. I am in the process of installing my microtech unit and would like to know what this is? Also, can it be removed? what would be the consequences? thanks

I'm guessing it's the coolant temp sensor if it's not very big, the larger one in that area is the oil pressure sender. Jack

 

Yep, that's the coolant temp guage sensor.
