Dual Pole Sensor

Single Pole Sensor

Installation Notes

• Installation should only be done by experienced personnel
• Disconnect the battery before doing any work to vehicle electronics
• For best accuracy
• connect ground as close to signal source as possible, for single pole sensors
• connect sensor ground as close to DIGIFIZmini as possible, for dual pole sensors
• One relay and one fuse are enough for up to ten DIGIFIZminis
• Crimping wires should always be preferred to soldering
  
• Don't connect a DIGIFIZmini to a sensor which is also used by a different gauge
• Supported single pole temperature sensors: 027 919 501 (12V 120°C), 049 919 501 (12V 125°C)
• Supported dual pole temperature sensor: 028 919 501 C (BERU ST118), 251 919 501 D
