Where is the relay switch on a 1988 Chevy Tahoe s10 truck?

The 1988 Chevy Tahoe (also called the S10 Blazer) lacks a traditional "relay switch" because it uses relays that are integrated with the fuse panel. Different relays and fuses control various electrical components, such as the headlights, fuel pump, and starter. These relays and fuses are typically located inside the fuse box under the hood, next to the battery. Please note that some S10 Blazers may also have a relay center in the passenger compartment, which may house some of the relays if the under-hood fuse box does not have enough space for all the circuits.
