Convertible Top Not Working

I have a 1967 Barracuda Convertible. It has a power top and the switch will not actuate the motor. I have done no testing to see if I have power to the switch or motor because I'm thinking this thing has to be fused somewhere.

I did stick my head up under the dash just long enough to find out there is a rather large wire that runs from the back of the ALT gauge to the switch without ever going through the fuse box. Wow!

I have a factory service manual for this car but it does not show any of the wiring detail for the convertible top. It's easy to troubleshoot but I wanted to go for a drive today with the top down. Anyone have a "quick fix"?
