Haltech Toyota A340 PRNDL Signal Converter

The Haltech Toyota A340 PRNDL Signal Converter (part number HT-038010) is designed to help you integrate your Haltech engine management system with a Toyota A340 automatic transmission. If you're swapping a Toyota A340 into a project or using a Haltech ECU with this transmission, this converter is what you need to properly read the transmission's gear position (Park, Reverse, Neutral, Drive, Low) signal. Without it, your Haltech ECU won't know what gear the transmission is in, which can affect tuning and certain engine functions.

This converter takes the complex signal from the A340's PRNDL switch and translates it into a simple, usable format for your Haltech ECU. It's a well-built component that ensures reliable communication between your transmission and your engine management system. Proper gear signal reading is important for features like electronic throttle control and certain safety parameters that rely on knowing the transmission's state.
