Rubicon problem(s) indicator light or ?

Hi everyone, I have not logged in for some time because my wonderful Jeep is so trouble free, until now. I had just said to my wife how much I loved my Jeep because it is not fussy, just runs and does what it is supposed to do.
Yesterday my wife and I had a little mountain adventure that involved getting (almost) stuck in snow. To get free I had to "exercise" the Rubi pretty hard. Not abuse , but in and out of 4hi and 4lo, as well as in and out of differential lockup. This went on for several miles until we got clear.
When I got home and started to turn into my drive I realized that it was in 4wd. The dash indicator was not on, so I had not noticed it on the road until I turned sharp. As I fiddled with the lever I could get it to intermittently go on , but it would not stay. This also means I can't access the locking differentials, since they will only operate in 4wh-lo.
So I put it on the rack and tried to adjust the shift linkage, thinking that maybe I had been a little rougher than I intended. Now I have no 4x4 light at all. Now this may be a dumb question, but where is the switch that talks to the indicator? The Chilton manual seems to be useless. It only shows that there is one, not where it is or how to check it.
I am sorry if this has been answered before, I couldn't seem to find it. Thank you for any help you can give. I still love my 2004 Rubi, but I may not brag on it as much. ( where it can hear me)

I'm not positive about the rubi and it's t-case, but dead center up top on the t-case is a sensor for the 4wd light, follow the wires heading up there

And all those other Latin and Greek phrases that mean don't mess with me, I am a bad ass that knows Latin and greek phrases!

I had a similar problem with my 06 Rubicon. This thread helped
I shopped around and found it and an new oring for around $50. Believe it was allmoparparts or something like that. Pretty cheap to ensure your lockers work when you need them. Give the top of the transfer case a good shot of brake cleaner followed by compressed air should keep any dirt from falling in when you remove the bad switch. Best access was from the front, I did not have a 1 1/2 inch socket or stubby wench so ended up using a pair of channel lock pliers.

Well, it evidently is not a bad switch. I jumped the wires with a paper clip as suggested and the 4wd light stays dark. Next I will check out the light in the dash. While I am in there I intend to do the Rubicon locker bypass using a couple switches. I opened the control area and found a whole lot of twisted up wires that someone has clugged in. I have no idea what they are supposed to do. One of them makes a relay click on the firewall, a relay that has been added for something.??? So I guess at least I can clean up the wiring and learn something about my Rubi.
