Upgrade your heavy-duty truck’s communication system with the REFURBISHED Kustom Truck Data Management Processor (Model GPLM-04), a patented, state-of-the-art device designed to bridge J1587 and J1939 data link communication. Engineered for seamless integration, this processor translates analog J1587 signals from engine ECMs (common in older engines) to digital J1939 signals used by modern Peterbilt and Kenworth cab electronics, ensuring fully functional dash switches and gauges. For example, it converts J1587 engine oil temperature signals to J1939 for accurate gauge display and downgrades J1939 engine brake switch signals to J1587 for ECM compatibility. Introduced in 2012 and continuously improved, the GPLM-04 boasts a low failure rate (<1%), offering reliability for custom builds and fleet upgrades. Ideal for mechanics and fleet owners, this refurbished processor restores compatibility between engine and chassis electronics in Class 8 trucks. Note: Confirm compatibility with your truck’s engine and chassis electronics by contacting Kustom Truck.
