uh yes im sorry
You are right...on pipe is fan switch
under thermostat housing there is sensor (I think that one for dash) indicator)
but on top od thermostat housing is sensor (for ECU)
Im not shore witcih is witch now but if you dissconecct one and indicator on dashboard fell down other one is for ecu
ther is also IAT sensor for intake air temperature and that one is on rear of intake
