Let me know what you find... Does your 4L work? Mine still works fine with the exception of the 4H not working. Wish I could manually engage that one.

I'll continue to look at everything and try to trace the wires back every chance I get but that will have to come in sperts do to lack of time and or patients. Besides i'm a little more worried about the front axles for the moment. Only the drivers side is bad but the boot on the passenger has a hole so getting that done is priority.
