What are these

In the attached picture (hopefully attached). What is the wire harness with all the blue wires and what is the black box that the arrows are pointing to?? This is behind the driver's kick panel.

My truck does not have these and i'm wondering why...

 

no pic...

 

Black box appears to be the 4wd computer. Not sure about the wires. Check where they connect and then we can look at a wiring diagram from the FSM.

 

No. The 4wd drive computer is in front of this black box. My truck has the plug for this foam-covered black box and the plug for all these blue wires but the box and the male part of the blue wires are missing. I'm trying to get to the bottom of larger problem which is that my e-locker and ABS are not working. See my previous post 'no locker or ABS' (or it was something like that....)
