Picked up four as well, even though they don't have an immediate home on my EMR II. A few thoughts that others may be interested in:
1. I have a couple light day packs/hydration packs that have a waist "belt" that is just webbing. These could slip over nicely and add some functionality.
2. Adding them on an AGC bino harness on the side straps. Some guys have done this with the FHF pouches, so this may be a cheap alternative.
3. May not work at all, but am going to try them threaded on the horizontal compression straps of the EMR II. Might be nice to have a small, dedicated pocket on the outside of the pack researved for just "x" (mini med kit maybe?).
4. If all else fails, they would make decent mini-mini-ditty sacks for the truck, pack, tool box, etc.
Coudnt really go wrong for $1.
Heck I bought some even at a buck. Figured odds/end pouches after I cut off the back stuff or maybe sew a narrower channel to fit a strap through.
But to answer no they don't connect on PALS, there is a loop on the back the full height of the pouch to apparently have gone over the full belt perhaps? It's like a 4" tall sleeve. There is a strip of hook Velcro on the back as well. There is a single zipper pull intended to close toward the rear of the pack when on a belt thus the left/right designation.
