Might be a generic ignition switch. I've not seen anything in the shop manuals where the switch needs or could even make use of a ground. Maybe 62 is different I can't thiunk of what might need a ground. The switch is power in, then ignition 1 & accessory terminals get connected when in key is in Run
ignition 2 and starter relay terminals get connected when key is in Start.
I'm assuming Wi-Fig is a phone correction LOL
