Liguori Drag Racing Custom Race Harness for FuelTech – Motorcycle

A custom race wiring harness designed and built by Liguori Drag Racing for your FuelTech-equipped motorcycle. Each harness is laid out around your motorcycle, component locations, and the way you want to control your race systems.

What's Included

Harness design labor: planning the wiring layout, connector locations, and circuits around your motorcycle and build requirements.
Harness build labor: building and assembling your custom race harness.
Harness materials: Tefzel wire, heat shrink, wire and connector labels, and new connectors needed to build the agreed harness.
ECU programming: configuring the applicable inputs, outputs, and control functions for your build.
Base tune: an initial ECU calibration for your combination. A base tune is a starting point; final tuning is not included.

What Happens After Purchase?

After you purchase a harness, we will contact you to review your motorcycle, confirm exactly what components are needed, and discuss how each system will be controlled.

We will confirm the component list, connector requirements, input and output assignments, and any additional circuits before finalizing the harness scope.

Additional costs may apply depending on your build, special requests, additional circuits, or changes to the agreed scope. Any additional charges will be discussed with you.
