This kit is compatible with 1996-2010 Softail, 1996-2011 Dyna, 1996-2013 FLT/Touring, and 1996-2013 XL Sportster models. It is not compatible with 2011 and newer models that feature CAN-bus or HDLAN wiring systems. Always verify your specific model year and wiring configuration before ordering.
You'll need an extension kit if you're relocating your handlebar-mounted turn signals or installing aftermarket handlebars that sit higher than stock. Without the extra length, your factory wiring harness may be too short to reach the relocated signals, resulting in improper connections or signal failure.
Most 2011 and newer Harley-Davidson models use CAN-bus or HDLAN wiring systems, which are not compatible with this MCS extension kit. We recommend contacting our support team with your specific VIN or model details to confirm compatibility, or consider alternative solutions designed for modern wiring systems.
Installation depends on your mechanical experience. The harness is pre-assembled, so you mainly need to disconnect the stock turn signal connectors, route the extension cable to the new signal location, and reconnect. Basic electrical knowledge and hand tools are typically sufficient. If you're uncomfortable working with motorcycle wiring, we recommend having a professional technician handle the installation.
The '+4 inch' designation refers to the additional length this harness provides beyond your stock wiring. The complete harness length allows for relocation of handlebar signals when used with aftermarket or higher handlebars. For exact measurements, we recommend checking the product specifications or contacting our team.
No. This is purely a wiring extension that maintains the same electrical connection and signal integrity as your factory setup. The +4" length extension does not reduce voltage, brightness, or operational function of your turn signals. All original safety features and signal performance remain unchanged.
Absolutely. This extension kit is perfect for custom builds including bobbers, cafe racers, and other modifications that involve handlebar relocation or higher handlebar installation. As long as your motorcycle matches the compatible model years listed and doesn't have CAN-bus wiring, this kit will work for your project.
