Product Description

The Haltech HT-038010 is a specialized signal conversion interface designed to interpret the PRNDL (Park, Reverse, Neutral, Drive, Low) range selector signals from a Toyota A340 automatic transmission and translate them into a single analog 0-5 V signal. This makes it compatible for direct reading by modern ECUs such as Haltech's Elite or Nexus series without requiring complex logic or engine-side programming for gear-selector states.

Installation entails wiring the 8 digital outputs from the A340's PRNDL range selector to the corresponding inputs on the converter. The module then synthesizes those into one analog output for ECU input. The included DTM12 connector and mating pins help retain a semi-OEM wiring approach. Ideal for custom ECU setups, retrofit builds, or race transmissions where you want the ECU to know the gear state in real time.
