I am looking to install a aftermarket gauge pack on my 2002 Impreza which consists of a Oil Pressure, Water Temp and Voltmeter. I have installed the oil pressure gauge and am about to install the water temperature sensor. The problem that I have is that there's only 1 place to get the coolant temp and it currently is taken up by the factory water temp sensor. My plan is to take it out and screw in a T type connector and then screw in each sensor into this T connector. My worries at the moment is that since the factory sensor will no longer be submerged in coolant that it will make the computer believe the engine is cooler than it actually is. Am I correct or do you think its nothing to worry about?
Also is there any other place that one can install a second water temp sensor?
Thanks Gerald
