since the actuating solenoid is brand new, it should work (not always, but lets hope it does). my next step would be to check the wiring that controls the soleniod, and make sure that its getting power. is there a fuse for the switch somewhere? i havent looked into that, but that would be my first step.

If one wire has 12 volts the other wire will need to get to ground. Does the 4wd switch provide the battery or ground? I don't know, just asking.
