Those pics shown without the aftermarket add ons are exactly like my 92 70 series.
Picture 6 looks after market, in some other series that is power/sport mode, it hangs on to the gears longer in an auto box before changing. Maybe someone replaced with the on/off switch, just a guess.
Picture 7 often in jest referred to as the ejector seat button.
Nothing to do with overdrive which should be on the shift.
The red button is to enable an auto model to disngage and be pushed around a workshop etc.
