Are you referring to the circuit breaker panel inside the passenger compartment footwell on the lower firewall?

There is only one relay near that panel, the 3-pin dash indicator relay, C5SZ-13A366-C.

The parts diagram shows three two-pin circuit breakers but they are not labeled.
They can be identified by the rating (stamped on the side) and the colors of the wire attached.
1. heater circuit breaker is 30A, 1.96"x.4", C1VZ-14526-C.
2. brake light circuit breaker is 15A with a green/red 14 ga wire, 1.07"x.4", C6SZ-14526-A
3. horn & ammeter 20A , 1.07x.4. C1VZ-14526-B
.
The turn signal and brake relays are located in the trunk on the rubber pad, mounted high in the left rear fender.
