Tether Anchorage Hardware; Front Passenger Seating Position - Ford 2000 E-150 Owner's Manual

Some manufacturers make safety seats that include a tether strap that
goes over the back of the vehicle seat and attaches to an anchoring
point. Other manufacturers offer the tether strap as an accessory.
Contact the manufacturer of your child safety seat for information about
ordering a tether strap.

Children should be placed in the rear in an appropriate child
safety seat that is properly secured to the vehicle.
Rear-facing infant seats must always be secured in the rear seat.
In vehicles without a rear seat, a rear-facing infant seat should
be secured in the front seat only if your vehicle does not have a
passenger side air bag or your vehicle is equipped with a passenger air
bag deactivate switch and the switch is turned to "OFF."
When using forward-facing child safety seats in vehicles with
only two seating positions so the forward-facing child safety seat
cannot be placed in the rear of the vehicle, move the passenger seat as
far back from the instrument panel as possible.

Front passenger seating position

The front passenger seating position does not require any tether
hardware. The tether can be attached directly to the rear of the front
seat.
