555 x Syvecs Transfer Case Temperature Sensor Harness

555 Engineering is proud to announce Syvecs AWD Controller Temperature Sensing!

After months of road and track test development between 555 Engineering and Syvecs the GRC AWD Controller can now read transfer case temperatures real time via our in house manufactured harness and temperature sensor. As would have been intended by the original Toyota drivetrain team - protect your drivetrain using actual measured values instead of the calculated inferred value that the OE controller uses.

This temperature harness will require some hardware rework for normal Syvecs controllers not purchased from 555 Engineering to work as well as an in-house firmware update.
