These wire connections are from the OZ w/shop manual TP832 1971wiring diagrams for a Mini K
Lighting Switch
2 Red wires terminal7 - lighting sw to splice 1/ body junction to light sw
1 Blue wire terminal 8 - lighting sw to dip sw
1 brown wire terminal 4 - lighting sw to ignition sw (main incoming supply to light sw and ignition sw/ignition ON circuits)
1 Red wire terminal 1 - lighting sw to main junction for tail lights, parkers and instrument lights
Wiper Sw
1 Green/yellow wire terminal 8 - wiper sw to wiper motor
1 Black wire terminal 6 - wiper sw to dash earth
1 Black/green wire terminal 1 - wiper sw to wiper motor
The wiper switch colours are not consistent with your colours for the green yellow wire so maybe ?????? the red/green wire was replaced with a green/yellow wire (by BMC). My S has the later type wiper motor and it uses red/green wire as well. But I can't pull the dash sw panel out to check at present.
The light sw connections seem to be the same but the wiper sw???
According to the Lucas wiring colour guide (do a google search for Lucas wiring colours) green/yellow is usually associated with heater motor circuits. You haven't mixed up some of the wires? You haven't got a green/red wire attached to the ON side of the ignition sw?
At least this may give you a start
