Think this may be different. Issue ive been told on the 4th pos nothing works no lights or ignition but if put into park the lights work

i just wanted to check if the key ignition is working but not sure which pins to check

Ive cleaned it and all contacts, couldnt visibly see any issues

Not sure about the X90 specifically, but the light switch contact will probably also make in conjunction with the ignition switch contact (lights on when engine on). Also, not sure if the switch grounds to the body of the switch, or one of the contacts would be ground. You’ll have to continuity test various switch and contact positions to see what changes as you turn the key.

Not sure if this will help.
