Installing a ROGUE® Motorcycle Gauge on your 1998 Harley-Davidson FXDWG Dyna Wide Glide or FLHR Road King is an effortless way to restore your bike's instrumentation or complete a custom upgrade.

To ensure a smooth installation, we recently created an Add-On Wiring Kit designed specifically for these Harley-Davidson models, providing the connections needed to power your gauge while accessing the factory speed sensor.

We were getting questions and comments from customers for this exact year make and model and wanted to provide an option for them that makes installation easier. We have also seen a lot of interest recently in similar ROGUE® wiring harnesses that have been selling extremely well.

The 3-foot Add-On Wiring Kit plugs directly into your Harley's factory wiring harness using plug-and-play connectors. Instead of cutting, splicing or modifying stock wiring, the harness installs securely between the original connectors for a clean, reliable installation. If you're replacing a worn factory gauge or upgrading your motorcycle's factory setup, this harness helps simplify the process while maintaining an OEM-style appearance.

Built for durability, the harness features 18-gauge automotive-grade wiring that stands up to changing road conditions and everyday riding. The black, orange, yellow and white wires are color-matched to the factory wiring, making installation more straightforward and helping maintain an organized wiring layout beneath the tank or fairing.

It is specifically engineered for use with the ROGUE® Motorcycle Gauge Series, an exclusive lineup of motorcycle gauges designed to match the factory appearance of Harley-Davidson monitoring devices.

Each ROGUE® gauge has factory-inspired styling with a matching faceplate, housing, lens, display and illumination. An integrated LCD display provides an odometer, trip meter and stock indicator functions, delivering modern functionality while preserving the classic appearance of your bike.

If you're installing a ROGUE® Motorcycle Gauge on a 1998 FXDWG Dyna Wide Glide or FLHR Road King, this wiring harness provides the dependable power and factory speed sensor connections needed for a professional-grade installation with minimal effort or impact to your bike.
