Pontiac 1998 Trans Sport Owner's Manual page 93

I
There's
a
vinyl ,sleeve there;
to get
to the bracket, push
this vinyl sleeve aside slightly. You may need to remove
the staple in
the sleeve to do this. Anchor the top strap to
the bracket.
If your
vehicle does not have third row seats
and belts, or if you need to have an anchor bracket
installed for the center bucket seat in the second row, or
for the right-hand side of a 60/40 bench seat, you can
ask your Pontiac dealer to put it in for you. If you want
to install an anchor bracket yourself, your dealer can tell
you how to do it.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself.
