"Door open" switch location 1991 Accord EX?

Hello.

My driver's door switch is no longer working; the courtesy
light won't come on and, more importantly, I get no warning
if the lights are on or the keys are in the ignition.

Where is this switch located? I assume it is inside the door
itself (activated by the checkstrap perhaps?) but I don't want
to pull the door panel until I'm sure.

I have had no luck finding it in the factory workshop manual.

Thanks
