I don't know the sds system and whether or not it can support a 3 wire stepper motor but the 2 wire is an on/ off switch. There should be a warm up "curve" in which the valve is open during a pre determined set of temp values.it is not important for the settings to be the same as the temp on your cars dash as it is only used for warm up and enrichment if the coolant( oil) gets too hot. I would disconnect power to the valve and see what happens when cold
