The wiring is simple mate
There is the wiring for the dash
He fog lights and heated screen buttons (they are a right bastard to get out, you have been warned )
The heater knob is simple
Fag lighter
Stereo
Light for the ash tray
Light for the glovebox
Possibly the button on the fan slider if it's 90 spec onwards but that stays on the slider panel from what I can remember
Easy as pie, with the correct screwdrivers I could probably do it all in about 30 minutes
