FORD 2002 F-550 v.3 - Manual (Page 123)

Tether anchorage hardware kits (part number 613D74) including
instructions, may be obtained at no charge from any Ford or
Lincoln/Mercury dealer.
If you have a Super Cab or Crew Cab, Ford recommends you attach
tether safety seats in the rear seating position (if possible) with the
tether strap attached to the tether anchorage bracket as shown in the
instructions provided with the tether anchor kit.
Tighten the anchor according to specifications. Otherwise, the
safety seat may not be properly secured and the child may be
injured in a sudden stop or collision.
Attaching child safety seats with tether straps
Most new forward-facing child safety seats include a tether strap which
goes over the back of the seat and hooks to an anchoring point. Tether
straps are available as an accessory for many older safety seats. Contact
the manufacturer of your child seat for information about ordering a
tether strap.
The passenger seats of your vehicle may be equipped with built-in tether
strap anchors located behind the seats as described below.
The tether anchors in your vehicle may be straps on the seatback or an
anchor bracket on the rear edge of the seat cushion or an anchor bracket
mounted to the body shell on the back panel.
The SuperCab rear seat has three straps behind the top of the seat back
that function as both routing loops for the tether straps and anchor
loops.
The tether strap anchors in your vehicle are in the following positions
(shown from top view):
Attach the tether strap only to the appropriate tether anchor as
shown. The tether strap may not work properly if attached
somewhere other than the correct tether anchor.
