Junction Block: Description
An electrical Junction Block (JB) is located in the left end cap of the instrument panel. The JB combines the functions previously provided by a separate fuse block module and relay center. It also serves to simplify and centralize numerous electrical components, as well as to distribute electrical current to many of the accessory systems in the vehicle. It eliminates the need for numerous splice connections and serves in place of a bulkhead connector between many of the engine compartment, instrument panel and body wire harnesses.
The JB is positioned on a mounting bracket up and under the left instrument panel. See Fig 1. It is secured by three screws. The JB is concealed behind the left instrument panel endcap. The left instrument panel endcap is a snap-fit fuse access cover that conceals the JB fuses and includes the fuse layout to ensure proper fuse identification. The left instrument panel endcap must be removed to access components other than the fuses in the JB.
