G.T. Car Parts provides upgraded remanufactured fuse boxes (also known as a fuseboard, fuse panel or relay assembly) for Ferrari 550 Maranello and Barchetta, sold on exchange basis.

We replace the factory adhesive-laminated multi-layer circuit boards with a new single printed circuit board (PCB) that has a greater amperage capacity and is more durable than the original. We reuse the original plastic fuse box housing, which is why we sell these as re-manufactured rather than new items. If your housing is damaged, in most cases we can provide a good used one from our stock at additional cost.

Manufactured exclusively for G.T. Car Parts, all our re-manufactured fuse boxes use rigid modern PCBs with updated materials and revised electronic designs. These boards address common failure points while maintaining original appearance and connection style. Our design eliminates common problems of burned out connectors/traces/solder joints caused by original design flaws, vibration fatigue, peeling board layers, and/or hidden corrosion between layers.

Installation is exactly the same as the factory unit. Our boards do not require any modifications to factory wiring or connectors. We do suggest that when installing a new fusebox you should evaluate the condition of your existing factory wiring harnesses and connectors. Cleaning and replacement of wiring harness components as needed will ensure best performance from your new fusebox.

Compatible with all 550 models

Our fuse boxes/boards are compatible with 550 Maranello and Barchetta models sold in all markets. Our fuse boxes are designed for direct “plug-and-play” compatibility with the factory wiring and relay configuration. Any aftermarket modifications or electrical faults should be corrected before installation of a new board.

Our latest design, based on years of experience

In October 2020 we introduced an updated fuse box PCB design for 550s. Based on more than 10 years of experience with these fuse box rebuilds, these new versions retain all the advantages of our classic “green board” PCB rebuilds with some added updates to allow quicker rebuild times, higher quality and even better electrical performance.
