JB,
The cables are to keep the two rams in "time" -- that is to say they form a pantograph linkage to keep the slide square and even as it moves in and out. The slide rooms are adjustable for fit to the coach, floor level, etc. so you need to look at the information that is in the Power Gear DeWald Hydraulic Slide Out Systems parts and installation manual. Here is a link:

and the adjustment information begins on page 20...
What is the issue with your slide, or are you just collecting information for a future need?
