Glacier Diesel Power 2003–2007 Dodge Ram 5.9L Cummins 18" Fuel Rail Pressure Sensor Extension Harness (0307-RPS-XH)
Description
Converting your 5.9L Common Rail Cummins to a 6.7L fuel rail requires more than just swapping hardware. Because the 6.7L fuel rail pressure sensor is positioned differently than the factory 5.9L setup, the original wiring harness is not long enough to reach the new sensor location.
The Glacier Diesel Power 18-Inch Fuel Rail Pressure Sensor Extension Harness is specifically engineered to bridge that gap, providing a clean, plug-and-play solution when installing a 6.7L fuel rail on a 2003–2007 5.9L Cummins. No cutting, splicing, or modifying your factory wiring is required.
Designed as part of Glacier Diesel Power's proven Mega-Rail Conversion System, this extension harness makes installation straightforward while maintaining a factory-style electrical connection.
Features
- Designed by Glacier Diesel Power
- Part Number: 0307-RPS-XH
- Fits 2003–2007 Dodge Ram 5.9L Common Rail Cummins
- Required when installing a 6.7L fuel rail on a 5.9L engine
- 18-inch extension length
- Plug-and-play installation
- No cutting or splicing required
- Factory-style electrical connectors
- OE-quality wiring and terminals
- Made specifically for GDP Mega-Rail conversions
Why Do You Need This Harness?
The factory 5.9L fuel rail pressure sensor connector was never designed to reach the location of the larger 6.7L fuel rail.
Without an extension harness, installers are often forced to stretch the factory wiring or splice additional wire into the harness—neither of which is ideal on a critical engine management circuit.
This extension harness provides the additional length needed while maintaining a secure, reliable connection.
Benefits include:
- Correct harness length for 6.7L rail conversions
- No wire cutting or splicing
- Clean, professional installation
- Factory-style connectors
- Protects the factory engine harness
Glacier Tech Tip
This harness is only intended for 2003–2007 5.9L Common Rail Cummins engines using a 6.7L fuel rail conversion.
It is commonly used during installation of the Glacier Diesel Power Mega-Rail System or Mega-Rail Installation Kit and is one of the required components for a proper conversion. If you're sourcing your own 6.7L rail and injector lines, don't forget this extension harness—it prevents unnecessary wiring modifications and keeps the installation looking factory.
Why Glacier Built It
Rather than asking customers to cut and extend their factory engine harness, Glacier Diesel Power engineered a dedicated extension harness that plugs directly into the OEM connectors.
The result is a cleaner installation, improved serviceability, and greater long-term reliability. It's a simple component, but one that makes a major difference in the quality of a Mega-Rail conversion.
Applications
Fits:
- 2003 Dodge Ram 2500 5.9L Cummins
- 2003 Dodge Ram 3500 5.9L Cummins
- 2004 Dodge Ram 2500 & 3500 5.9L Cummins
- 2004.5 Dodge Ram 2500 & 3500 5.9L Cummins
- 2005 Dodge Ram 2500 & 3500 5.9L Cummins
- 2006 Dodge Ram 2500 & 3500 5.9L Cummins
- 2007 Dodge Ram 2500 & 3500 5.9L Cummins
Designed exclusively for 5.9L Common Rail trucks converting to a 6.7L fuel rail.
Kit Contents
Includes:
- (1) Glacier Diesel Power 18" Fuel Rail Pressure Sensor Extension Harness
Important Notes
- Fits 2003–2007 5.9L Common Rail Cummins applications only.
- Required when installing a 6.7L fuel rail on a 5.9L engine.
- Plug-and-play installation.
- No cutting or splicing of the factory wiring harness required.
- Designed for use with the Glacier Diesel Power Mega-Rail System and Mega-Rail Installation Kit.
Common Failure Point
One of the most common mistakes during a 6.7L rail conversion is attempting to stretch the factory fuel rail pressure sensor wiring to reach the relocated sensor. This places constant tension on the wiring harness and connector, which can lead to broken wires, intermittent electrical faults, or sensor communication issues.
The Glacier Diesel Power Extension Harness provides the correct length for the conversion, eliminating unnecessary strain on the factory harness while delivering a clean, reliable installation.
