just bought this 96 sierra with push button 4wd controlls. the po has a switch wired to engage 4wd but only engages high . i traced the wire and it goes straight to the actuator on the front axle. so im assuming that the tcase is always in 4 wheel drive and the switch is just locking the axle in . does anybody have a wiring diagram of the wirng from the sitch to the tcase and then to the axle. i would like to be able to use my buttons as the were intended .
