Question about Motorcycles
There is a short circuit that wasn't caused by the wiring harness but is caused by either something wrongly connected or by a faulty component.
The advice above is good but I suggest you begin by obtaining a wiring diagram and ensure every wire is going to where it is meant to go as a first and very important measure.
The bike probably has a negative ground system so the negative battery post would go to the frame, etc. and a battery positive would go to the starter relay or solenoid.

Thanks for the details, they do help. Is there a way you can disconnect different electrical circuits from the battery? Like Disconnect the lights, horn, or other components then start adding them back until you find the circuit or group of wires that causes the short. Because it seems you have a short somewhere, or something really putting a load on that 30 Amp fuse. So I'd break the circuits down to smaller pieces so that when you reconnect the lights, or starter, or whatever....that the fuse pops and you know the circuit causing the issue. You may have to open engine components like a magneto to isolate the circuits. But it shouldn't cost you anything except time.

Was the old fuel pump bad? It might be worth the cost to replace the ignition switch. The wires to the fuel pump would be a second guess if the old pump was bad and burnt the wires before the fuse went. When you eliminated the fuel pump you also eliminated the wires to the pump and it started. Then you replaced the pump, but not the wires. The ignition switch is the other end of the circuit.

I am about to have the same problem with my 2002 ZX2. My shop called the Ford dealer and they can replace it for $450.00...
seems like an awful lot for a battery cable.

SOURCE: the horn doesn't blow. at
Your problem is most likely a defective clockspring assembly. This is also called "spiral cable assembly" it is located just under the steering wheel on the steering column and makes the connection between the main wiring harness and the circuits for the air bag and the horn. I cannot give you wire colors because your question did not mention year, make, model, engine size or whether the vehicle is equipped with cruise control or not. (cruise control makes a difference in the clockspring assembly used on your car.)
Anyway, the air bag and steering wheel has to be removed to fix it.
