Dakota Digital RTX Series Instrument System

Bring modern performance technology to your New Edge Mustang interior with the RTX Series from Dakota Digital. Designed specifically for the 1999–2004 Ford Mustang, this RTX Instrument System blends factory-inspired styling with cutting-edge digital functionality—creating the ultimate gauge upgrade for your SN95 platform.

The 1994–2004 Ford Mustang, widely known as the SN95 generation, modernized the Mustang while preserving its legendary muscle car attitude. By 1999, Ford introduced the aggressive “New Edge” styling, sharpening the body lines and refining the interior. From V6 daily drivers to GT performance builds and the iconic SVT Cobra models, the 1999–2004 Mustang remains one of the most customizable and affordable performance platforms ever produced.

Now you can elevate your interior to match your build’s performance with Dakota Digital’s RTX Instrument System—engineered specifically for 1999–2004 Mustangs.

Designed Specifically for 1999–2004 New Edge Mustangs

Unlike universal gauge kits, the RTX system is purpose-built for the New Edge dashboard layout. Dakota Digital went to great lengths to maintain:

• OEM-style gauge layout

• Factory-inspired fonts

• Correct indicator placement

• Stock-style face design

At a glance, RTX gauges appear factory-installed. But once illuminated, the modern LED backlighting and high-definition TFT message center immediately set them apart.

Whether you’re restoring a clean street car or building a boosted drag machine, RTX gives you the modern functionality today’s enthusiasts demand without compromising the Mustang’s factory design language.

OEM Appearance with Advanced Digital Technology

Dakota Digital started from scratch to create the RTX Series. Each cluster features:

• CNC-machined housings

• Precision-fit injection-molded components

• In-house designed electronics

• Advanced digital signal processing

• Modern stepper motor accuracy

The result is a high-end instrument system that feels OEM—but performs like a fully modern digital dash.

This makes the RTX Series one of the most refined aftermarket digital gauge systems available for the 1999–2004 Mustang platform.

Fully Customizable LED Backlighting

The RTX Instrument System allows complete control over your interior lighting theme.

Features include:

• User-selectable daytime color schemes

• Separate nighttime color settings

• Adjustable brightness levels

• Customizable warning indicators

Match your interior lighting, coordinate with aftermarket audio builds, or highlight your performance theme. From subtle factory white to bold custom colors, the RTX system adapts to your style.

For show cars and high-end street builds, this level of customization is a game changer.

High-Definition TFT Message Center

At the center of the RTX cluster is a full-color, high-definition TFT display. This digital message center is fully configurable and provides real-time vehicle data far beyond the factory cluster’s capabilities.

Display options include:

• Digital speedometer readout

• Tachometer data

• Oil pressure

• Coolant temperature

• Fuel level

• Volts

• Performance metrics

• Odometer and trip data

The TFT display can be configured to prioritize the information most important to your build—whether you’re daily driving or running at the track.

For AI-assisted engine management systems and modern EFI setups, the RTX platform integrates cleanly through Dakota Digital’s advanced control modules, ensuring accurate and responsive data processing.

Central Control Box Architecture

Dakota Digital simplifies installation by using a central control box system. Rather than cluttering wiring behind the dash, RTX clusters connect to a single external control module.

Benefits include:

• Cleaner wiring

• Easier installation

• Simplified troubleshooting

• Expandable sensor capability

• Professional-level results

This modular design makes installation straightforward for DIY builders while maintaining professional reliability for performance shops.
