off-white wire w/ connector below passenger compartment?

My Jimmy project is almost done! Just have some miscellaneous stuff to figure out.

There was an unattached off-white wire w/ a connector below the passenger side of the dash. It has some gray foam around the wire too.

Anyone know what this is to and where this hooks up? I haven't been able to figure it out yet.

No one knows what this is?

My current candidates are:

1. Passenger open door switch (currently no lights come on when the passenger door opens up)
2. glove box side light (but since it is a single wire, I wouldnt think it would operate a light)
3. ???

Sounds like the timing wire...(Connects the distributor to the ECM)

but my truck seems to be working fine with it unplugged.

When the front passenger door opens on a gen1 1994, are the floor lamps supposed to come on?

The other 3 doors all turn on the floor lamps under the dash, but the front passenger door does not.

Yes, it's supposed to come on, pull the switch in the door and see if both connectors are on.

Take a picture of it.
