Aw4 wiring options

Well i have been researching and i have found out how to lock the aw4 in 1st or second. Im wanting the most i can get out of this tranny and it seems like it has a lot of options. My question is what all homegrown stuff have you done to it?? Im wanting to be able to lock the torque converter at will also. Anybody got a wiring diagram of that? I do not want to buy a kit or anything, want to do all the wiring myself....thanks! And btw being able to lock the tranny in 1st or 2nd is super useful. Highly recommend it!
