This is a tough one. You have a short between the headlamp switch wiring and the ignition switch wiring.
Check the wiring under the Passenger Compartment Fuse box as well as te wiring under the Power Distribution Box next to the battery. Especially the wiring for the fuses and relays for the headlamp switch and ignition switch.
