Pro Start 3471 Thermistor Value

Hi all, does anyone know what the value of the thermistor is for the ProStart
Remot car starters. There is a connector on the side of my ProStart for a temp.sensor. The Prostart guys tell me its a thermistor but they don't know the value. To buy this they want 30 bucks plus shipping. Maybe some one out there has one or has a circuit diagram.

Thanks
