The bongo appears to have lots of blanked off switched to the left of the wheel. not sure if anyone else has investigated

I looked behnd these blanked off switched to find a couple of bundles of wiring anyone know what they MAY do.

you can see 2 large bundles of wires either side of the Black bundle of wires ( the black lot go too the rear screen demister) the two coloured bundles go to the blanked off dash .
hope that all makes sence
any ideas. ?
