Holley EFI 554-171 - Dual Range Current Transducer - 0-20A / 0-200A


Introducing the latest sensors to the Holley EFI line up – Current Transducers. These high-quality transducers can be easily installed to monitor the amp draw from any mission-critical component, such as fuel pumps, alternators, electric water pumps, or even inductive ignition coils. Both of the Holley EFI Current Transducers are dual range, meaning they can monitor both high and low amp current draw, with one sensor. They also have built-in mounting tabs, allowing you to mount the sensor virtually anywhere. Simply run the high load 12v power wire through the sensor, securely mount the sensor, and finally make your terminations to the ECU.
