on my laser, the small one on the t housing is for the guage, big one with 2 large perpendicular blades is ecu, and the one in the pic above goes in the rad to switch the fans on. i go to advance auto, and i had to explain the exact location of the sensor on the rad and what it looked like for them to find it in the comp. they didnt even know there was one there. odd.
