It's all from the same switch, the one you can see on the body/pillar by the latch.
It reports to the BCM (body control module) and the BCM tells the lights to come on and activates the door open display on the VIC - and it's also what triggers the alarm to go off if the doors are opened while security is on.
The wiring to the latch itself is only for the lock motor.
Just an FYI somewhat related to this: On early ZJs the interior lights vs VIC and security were divided up between the switch we're talking about and another one that the early ZJs had in the door hinge areas - but I can't remember which of those switches did which, LOL.
It seems like a really oddball problem, BUT - is this with the Jeep moving? ...or just running?
If it's while you're driving and actually turning left or right I'd think it might be bad door hinge pins allowing slight movement of the door itself which can trigger the switch if it's bad enough.
If it's just doing it by turning the wheel while you're not moving - then you've got an 'interesting' problem
