Starting at the backing plates and going forward my pb cables run along the inside of the frame and the passenger side crosses over just before the xfer case. From a top view the cable would be in a 'U' shape, all one peice. It is all open cable, except for about the first 2 feet out of the backing plate- the cable here is in a metal cable sheild. When the The cables end just out of the sheilds, there are some connectors to connect them to the main 'U' cable. I bought a longer piece of cable for the 'U'.
I am not sure what years did what, but at some point they have a little different set up where the pass side cable crosses over at the diff and they both run up the driver side frame rail.
Again, hope this makes sense to ya! I dont have a way to get you a pic or I would.
