Fuse/Relay Block

A wire from the battery to the Fuse/Relay Block is used to supply current to several fuses and timer/relays located in the Fuse/Relay Block. The Fuse/Relay Block includes up to four fused and up to two timer/relays. There is one cartridge fuse, one circuit breaker, two blade type fuses, one timer/relay, and ISO one relay. Internal connection of the Fuse/Relay Block circuits is accomplished by a network of hardwired connections. The fuse cartridges, timer relays, and fuses are available for service replacement. The Fuse/Relay Block unit cannot be repaired and is only serviced as a unit with the uni-body wire harness. If the Fuse/Relay Block is faulty or damaged, the uni-body wire harness assembly must be replaced. For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.

NOTE: If the unibody harness with the Fuse/Relay Block is being replaced with a new unit, be certain to transfer each of the fuses and relays from the old fuse/relay block to the proper cavities of the new fuse/relay block for proper power distribution. Refer to the FUSE/RELAY BLOCK in Wiring Diagrams for the proper cavity assignments.
