need to know if the one wire switch on the tstat housing on my 90 sc is a temperature sending unit used for the temp gauge or if its a coolant temperature sensor used by the pcm? i need to get a new one since i broke the old one installing a tstat.

its the one for the gauge, the one for computer is on the lower intake manifold on the passenger side next to the SC.

so the one ur talking about is for the GAUGE not the ECU.
