Can anyone with a seek outside pack tell me how the shoulder strap harness attaches to the pack bag? I bought a pair of shoulder straps and hipbelt from them to update an old Jansport frame and cant figue it out based on pictures I found on the web.

I know how the load lifters attach and the vertical straps on the hip belt attach to the bottom of the shoulder straps. Its the vertical strapsat the back of the harness I need info about.

All the pictures on the web have those straps disappearing behind the backband on the pack. Do those vertical straps attach to the cushy backband or do they attach to the back of the backpack bag itself?
