Usage Scenarios
Stealth ELD/GPS Installation
Unplug the factory green 9-pin port, connect it to this harness, and hide your tracking device behind the dash. Use the brackets to mount the new 9-pin port in the original dash location.
Professional Diagnostic Access
Keeps a standard 9-pin port available for technicians to run diagnostics, while a second device (like a dash cam or telematics hub) remains permanently connected via the hidden OBD2 port.
Port Protection & Longevity
Prevents wear and tear on the expensive factory dashboard wiring harness caused by frequent plugging and unplugging of diagnostic tools during fleet maintenance.
