Product Information
This RP1226 14Pin wiring harness is designed for heavy-duty trucks, splitting the RP1226 port into an OBD2 connector and multiple terminals for simultaneous connection of ELD devices, diagnostic scanners and fleet management tools.
Made of automotive-grade materials, it ensures stable J1939 data transmission for vehicle diagnostics and compliance.
Usage Scenarios
Stealth Fleet Management Installation
Unplug the factory OBD2 port, plug it into the harness, and hide your GPS tracker or ELD device behind the dash. Use one of the 14 brackets to mount the new port in the original location.
Protecting the Diagnostic Port
By relocating the factory port and replacing it with this harness, you prevent wear and tear on the vehicle's original wiring from frequent scanner plug-ins.
Multi-Device Support
Keep your fleet monitoring device permanently connected while leaving a 'dummy' or secondary port available for service technicians or emissions testing.
