Read all the door ajar posts, have a simple question

I've just bought a '03 4x4 Super Cab with the door ajar issue. Read all the posts and am no stranger to WD-40, PB Blaster, etc. What no one amazingly enough said, is WHICH LATCH has the electrical switch? With my Super Cab there are six latches and my first pass hasn't fixed the light issue, though it did release a sticking latch in the driver's rear door. Really thought I had it with that, but no. And I've looked at all of the drawings available for replacement parts to try and tell, but alas, no luck. Since my wife is not particularly fond of WD40 scent, I'd rather hit the proper spot then release a flood. Then again...
Thanks!

I believe that newer Rangers have magnetic switches inside the door.

being as the doors are the same from 93 to current rangers i would say that the latch is the same style and being as it is said for reg cabs ext cabs and four doors it would have to be the latch that is the same in all of them that is the one in the front doors
