1993 Ford Bronco My Fullsize Bronco will not engage into 4W

My Bronco had been sitting for about six months outside part of which was winter. During which time I might have started it only a couple of times. I remeber the 4x4 working when I first retired the vehicle, its the automatic push button that lit up. When I finally decided to get the Bronco going again to sell, I ran into a few problems. Possibly due to a dying battery my keyless entry was setting off my alarm and was killing th engine. I tried to trouble shoot it but every odd time I was able to get the car started and drive foward, if I slowed down or put it in reverse it would stall and so on so forth. I ended up taking out the alarm myself and did the best I could to reconnect everything. The car would start without a problem but I later came to find out that was only the half of it and I ended up needing a new TPS. Needless to say it was driveable again. I polished her up to sell, cleaned the engine with engine brite, thought I covered all the circuitry. Went for a ride in the car and decided to test the 4x4 had not done so since I first retired it. It doesn't work. I checked all the fuses and they are good. The indicator switch is not working and I am hearing nothing. Two things happened I think. Something got wet from when I washed the engine or was it possible that when I removed the alarm I could have messed up the wiring? Or maybe it is something altogether different. Sorry about the novel fellas, I don't know enough about trucks to know whats important and whats not. I would appreciate your insight.
