Default ECM seals

Hey guys, I tried looking for a thread about this, but I couldnt find one so Ill ask. I took the connectors off my ECM and sent the harness to Speartech. My question is about the small thin orange seals that are between the connectors and then ECM, they are all flimsy and not staying in place around the perimeter of the 'flange', and they dont stay when I try to position them. Has anyone had this issue and what did you do to take care of it?? Can I just use a really carefully placed small bead of silicone along there?? Thanks for the help!!!

They should stay on the harness side, not the ECM side, once put back on the harness side, it should stay in place.

They fit down inside the harness, around the colored plastic pin holders. Just carefully push 'em on, and down in there. You'll see how they fit once you start... it's pretty good.

Just be sure it is properly sealed, especially if you are using it in an F-body...dont ask me why I say that....
