Ignition switch / wiring

[Jean]

There is a chance that I'll need to replace this tomorrow, I've done the ignition lock cylinder before but not the ignition switch/wiring itself.

What does it take to replace it, does it come right off or are there security screws?

Also, is there two versions, srs and non srs or more?

Thanks

The switch comes off cleanly, though it will be EXCITING!!!!111 to get two small screwdrivers in the slots to disconnect it from the metal steering lock assembly. AFAIK for 87-91 US cars there are the two versions.
