To find it, you'll need to:
1. Check common relay locations: Look in the fuse boxes (under the dash and possibly in the engine compartment). While unlikely to be a dedicated "alarm horn" relay, it might be grouped with other accessories.
2. Trace the wiring: If you know the horn is activating (or if you can activate it to hear the sound), follow the wiring harness from the horn back toward the fuse box and other potential relay mounting points. You'll likely find a relay along the path. This requires some patience and electrical knowledge.
3. Consult a wiring diagram: A wiring diagram specific to your Corvette's year and any added alarm systems is crucial. These are sometimes available online through Corvette enthusiast websites or from restoration parts suppliers. The diagram will show you the relay's position if the alarm system was a factory-installed option.
4. Look in the owner's manual: If your manual survives, it *might* mention the alarm system (if present) and provide some hints on location.
Without more specifics about the alarm system's origin (factory, dealer-installed, aftermarket), pinpointing the relay is difficult. A visual inspection, wire tracing, and a wiring diagram are your best bets.
