On my convertible w/power top, the power lead to the switch goes to the fuse block and another wire to the horn relay (this connector plugs into the relay and the single wire connector removed from the relay plugs back into the bottom of the connector).
The power lead wire directly from the power top switch has an end that is inserted into the top center slot on the fuse block under the dash (it only goes in one way). That slot's power is fed by the upper left fuse holder and it has a solid piece of steel rod in the shape of a fuse. The wire feeding that slot is the one that goes to the horn relay.
I do not have the separate relay as described above and on most Camaro's.
When I first got the car and tried to get power to the top switch, I had the same problem blowing fuses and I thought someone had inserted the piece of steel rod to over-ride the circuit. I did some research in my repair manual of the electrical system and found this to be the correct way to hook everything up.
