Fuse Blocks
The power and ground distribution system used on the Saturn vehicles are fuse blocks.
These fuse blocks provide a home for mini and maxi fuses, relays, and electronic modules, eliminating the need for separate connections and mounting attachments. They are also a central connection point for major harnesses (Engine, Forward Lamp, I/P and Body). Inside the fuse block are layered buss plates that help reduce the number of splices in the harnesses.
With the advances in automotive electronics over the past few years, the size and complexity of wiring harnesses have increased. The fuse blocks help remove complexity from the wiring assemblies and provide a central location for circuit protection devices and relays. Fuse blocks help reduce the complexity while also reducing cost and mass. This is accomplished by reducing the number of cut leads, eliminating the need for in-line connectors and splice packs. This also helps reduce the bundle size of a wiring harness.
