Am i in trouble? I bought new ignition switch and it has some difference between original. What are those 2 wires?

Those are for the 'key in' buzzer.

Alright, so not important. The buzzer is not working so it wont do any difference. Thanks! No i gotta find some tool to remove those "anti-theft" screws.

Several ways to do that. One of the most common is to use a Dremel tool (or similar) to cut a slot in the head and use a screw driver on them. Others have used a hammer and punch, while yet other people will use a drill and drill the heads off.

I drill a hole in them and use a Craftsman 'Screw out' tool.

New ignition switch on place and working! I hammered the old screws off with flathead screwdriver, luckily they were not tight.

In new one, "anti-theft" screws have 5.5mm bolt heads wich can be snapped off easily. I wont snap them in case i need to remove that switch again. Nice to have reliable switch
