You're good brother. I'll try to walk you thru it.
Unhook the load lifter straps from the top of the shoulder pads where it attaches to the top of the frame.
Slip the hypalon sleeve over the top of the frame and move the common loops thru the top holes of the hypalon sleeve.
Reattach the load lifter straps to one of the loops in the position of choice. (Top, middle, bottom etc)
On the AMR bag find the horizontal straps that run from the front of the bag back to the corresponding loop on the side of the frame.
(Should be two vertical straps on each side that correspond to the 2nd and forth frame loops.
On the back of the bag you'll see a couple of 3 bar sliders near the bottom of the bag. Attach the 3 bar sliders to the corresponding common loops on the frame.
Hopefully that helps. If not, I might be able to shoot you a short video this weekend. I'm away from my gear until then.
