Ok I'll to explain this to you as best as I can. On the block at the back cab on the bottom there is a series of hoses, there are three close to the outside edge you will need to take the front one and the middle one off to get to the one inside hose fitting. That one hose second from the outside close to the cab remove it and swap it with the hose on the block close to the center of the machine on the rear corner. Then remove the hose on the outside rear corner and swap it with the hose on the front corner inside toward the center of machine. Be sure and swap the hoses on the bottom of the block where the pressure are.
I hope this helps, oh BTW if the color code tags are still there it is let me know where they are located should be pink,blue,green and red, I can't remember where they are located for factory control setup.

I just switch the pattern on my Link Belt 4300Q which is the same as Case 9050B. From the picture above switch A3 for A8 and A4 For A7. A4 is the hose in the center with an extension on it. You'll have to remove A7 and the hose between A7 and A8 and well as both of the adaptor fittings on those two hoses to get to A8. You may have to remove the hose on the opposite corner and unplug a pressure sensor to get to A4. BEFORE YOU UNHOOK ANY HOSES BE SURE TO RELEASE PRESSURE FROM THE HYDRAULIC TANK WITH THE PULL VALVE LOCATED ON TOP OF THE TANK NEAR THE FILL CAP.
