The wires under the sterering box are for your lights and horn.

There is a single glass fuse on the backside of the dash, drivers side. Check it. It it is broke the engine will crank but no spark. Your problem is more then likley extremly simple.
If the fuse is good, get a test light and with the ignition "on", touch the point plate inside the distributor. If it lights up that tells you there is power to the distributor (eliminating the electrical on the switch inside the car)
If it does not light up, trace back and see where the test light lights up, and you will find your problem.
