Slide fown the plastic trim directly under the leather and you'll see 2 screws, one front, one back. Undo them and the gearknob should lift up. Thats the easy bit - the wire for the o/d button wuns through the centre of the shift plate to a plug at the front. Remove the surround and you'll see 4 screws, you'll need to undo them and remove the bulb from its holder. follow the wires back from the bulb and you'll see they go over a clip. unhook it and the whole lot should lift up. Follow the wires from the o/d off switch to the plug at the front and unplug it. The plug right next to this is for the manu button, unplug that too. Feed the wire for the o/d light through the shit mechanism until it comes out - very tight, but it should fit ( think there is a couple of cable ties as well), then route the new wire back the same way and reinstall. When i changed mine i took the whole centre console and armrest off too - gives you a bit more room to work. Its a very fiddly job - have fun.
