It's pretty straightforward you just gotta be smart with how to get your screwdriver to some of the screws (mainly when re-installing)....

I'm not at home, but i shopped mine last month and it's still pretty fresh in my head....

To remove All the ramps (which you basically need to to do what you want, if you try to half ass it you could break or bend something).

First remove the up kick (top right) habitrail. It's two screws down on the PF and two tiny ones where it attaches to the entrance to the black diverter ramp.

Next remove the shooter lane habitrail. Two lock nuts under the PF near the shooter area, and two tiny ones where it attaches to the entrance to the black diverter ramp.

Now remove the two center "lock" habitrails. Unplug the switches (spade connectors right at the switches). Each habitrail has two screws at the lock area by the bumper, and two tiny ones where it attaches to the black diverter ramp.

Remove the large crossover habitrail. Same as above, a switch, two tiny screws at the diverter, and a screw or two on the right side.

Now unplug the two plugs under the PF where the wiring goes up into the black diverter ramp, remove the 3 (or 4) screws around the edge of the black diverter ramp, feed the wires up through the PF, shift the ramp around the diverter arms and you are done.

Once you are looking at it it'll make sense. it's way easier then it looks.
