very simple switch wiring on the 200s, no electronics at all.
useful wiring diagram in the back of haynes.
i experienced very bizarre and muddled window operation when i forgot to connect the window earths.
these earths are bolted down to the tunnel right at the very very back, basically under the ashtray at the back of the console.
if you undo the 4 screws under the cubby box/bag, pop the handbrake gaitor out, slide the switch panel over towards the handbrake and undo the screw underneath there, unscrew both gearknobs and remove the gaitors and rubber mat and undo the two screws near the radio, disconnect the handbrake cable and lift out the centre console, you will have good access to the wiring, and those earths at the back.
you do not need or want to disconnect the window wiring plugs from the switches, just pass the panel through the hole.
cheers!
