Undo six screws holding the plastic housing around the steering wheel (it separates in two halves). the ignition switch is held into the rear of the key barrel by one philips head screw. It's tight to get to but once removed the switch just slides out of the end of the barrel (key and lock assembly remain). Unclip the wiring socket and the ignition switch is in your hand. On my 97 Terrano ii the switch has the brand CLAUSOR and the number 911056.
