Dome Light wont turn off

I removed the drivers door panel to put the window back in the left track, I found 2 wires going to the lock, a black one and one that is a light green w/ black stripe. Made sure I was careful around it, and when I was done made sure the connector was still on etc. Put it back together, shut the door, and the dome lights wont kick off. I was wondering if this was for the door trigger?

Checked that both doors were closed, checked light dimmer switch to make sure that wasnt it, still on. So I pulled the fuse for the dome light. Any ideas?

Also I was wondering if those wires are for door locks, where would the keyless entry module be located?

Thanks!

What year is your truck, i know the door jamb switches are notorious for going bad in the rangers, i just had to replace my passenger side, also id probably start with the area you were working at and if you have a multi meter check the circuit for that particular door jamb switch and see if its actually working correctly with the door.

Another thought, after i put in some aftermarket doorlocks in my truck every once and a while iv noticed my dome light will stay on after closing the doors and i have to get in and just rock the key to acc and back off and shut the door again and it corrects it, im not sure what the reason is but its probably one of the actuators causing the latch to not move as freely as it should.

try spraying the latch on both doors with WD40 and then slamming the doors shut repeatedly. I mean SLAM them as hard as you can lol.
I did this on my truck last year because i had the same issue and it hasn't come back since.

I did this just a couple of months back at 99offroadrngr’s suggestion and it worked.
The door light and dinger would stay on in my 03 RNGR EDGE.
I sprayed the lock mechanism with White Lithium Grease through the lock area of the door, all good for now. Lithium Grease tend to hold on better and longer than WD40 but either should work.

Just thinking out loud and I am not an Electrical Automotive Tech or anything that might resemble one like some of the guys on here; my ideas are shooting from the hip and may need some refining based on different systems so take what I suggest with a grain of salt.

Even after you do the "spraying of the latch" thing, it may not help, the switch inside the door may be bad and need replacing but since it worked before it should now.
If after spraying, the light is still on, attempt to check out the power through the switch, remembering that the system is ground dependent. This means that there should be power in the door latch area but you may still have a bad latch switch; usually the latch fails on that is why you get the light on situation.
The power needs to flow through the switch to ground when the door is open or ajar so remember, once the leads are connected to check the working of the switch close the door and see if the power still flows through the switch. If if does then the switch is probable bad and needs replacing.

Connect the leads of the Multimeter or test probe from the ground side of the switch.
