Rear Seat Top Strap Anchors (Extended Cab Models) If your vehicle is a regular cab model, there is also a top strap anchor for the right front passenger position located on the back panel of your vehicle, behind the right front passenger seat. In order to get to the anchor, you'll have to remove the trim plug covering it. Once you have the top strap anchored, you'll be ready to secure the child restraint itself. Tighten the top strap when and as the child restraint manufacturer's instructions say. If your vehicle is an extended cab model, you'll find the top strap anchors for the rear seating positions near the top of the seatback. In addition to the top strap anchors, each seating position has a fabric loop at the top of the seatback that you'll use to route a top strap through. 1-44
