Bought and restoring a 70 cutlass convertible. Convertible top was not hooked up when I bought it, but was assured it works
What I need to know, help, is what runs between the battery and the switch? Is there a circuit breaker, relay, fusible link or some combination of the three? All the wiring from the switch back is intact
Thanks

 

From your horn relay, located on the driver side inner fender, there is red wire going to the circuit breaker located near the top of the brake booster. Then another red wire going in the firewall I think then to the switch.
Here is a link to some pictures of the wiring that may help sort some of it out for you.
