what temp are you talking about? I assume EGT's? You will need to install a egt system not hard to do check out koso gauges they are nice you can get them with water temp also
You will not have EGT or water temp as a factory option on your sled
All m series cats snow pro ones have built in coolant temp. Need to have gauge on mph and digital display for rpm, hold in on top two buttons or the two small ones never remember what buttons for approx ten seconds when let go there should be a v show up where odometer usually is showing the voltage output of the stator, press button three times I believe there is a 3 space and the temp. 3 157 example. I didn't know this till last year and someone showed me. I am assuming these are the inputs the ECM uses for different sensors. There nothing in the owners manual but you can double check just run with it on, let sled run hot and at approx 176 the coolant should start to flash on the screen letting u know sled is heating up
