Installing the tee nuts is a bit tricky, but I made a tool out of a 10-32 bolt and glued a length of copper wire to it to thread it through from the backside of the firewall. I noted that the lower right location was close to some triangle stock on the backside, so I trimmed the tee nut for that location. The jam nut is put on just hand tight to hold the bolt in position such the flat side of the modified bolt aligns withe one of the barbs. That way you can know where the barbs are relative to the holes when it's behind the firewall. The idea is to form a "U" in the end of the copper wire to loop it in and out the desired hole. Apply some 30-minute epoxy to the flange and barrel of the tee nut and draw it into position with the wire. You might want to practice this without the epoxy first.
