I wrapped it around the front of the seat. There is a bar going across the front that slides under the hooks to hold it in place and it has a small gap under it so it goes under there perfect without having to force the seat back into place. I know it is not the recommended placement (supposed to be 20° towards the rear) but, considering you would be fine with 4 points with no anti-sub strap I don't know that it matters too much. I like the 5th point to prevent the rest of the harness from riding up and ending up loose half way up to my chest.How did you mount the anti-sub strap? Thanks.
