After replacing the actuator on the front axle, I started having issues with the switch on the side of the transfer case not seeing that I had pulled the handle into 4hi or 4lo.
Quick trip to a pull-a-part junk yard with a set of wire cutters netted me an xtra plug that plugs into the actuator. I plugged that one into the actuator and ran wiring to a switch at the dash with a 20 amp inline fuse. Problem solved and has never let me down.
That being said, I have a ford high pinion 8 lug dana 44 laying here that I have been toying with throwing under the rig using the kit from sky manufacturing.
