side of the floorboard.

  Do not drill through any wiring. the air bag sen-
sor  wire  may  be  located  under  the  driver’s  seat. 
Drilling into this wire may disable the air bag sys-
tem, or may cause the air bags to deploy immedi-
ately, which may cause severe personal injury.
  failure  to  follow  these  instructions  may  cause 
property damage, personal injury or even death.

 

  Next, drill five ¼" holes at the points you marked. 

Drill through the carpet and the floorboard. Use caution 
to prevent the drill bit from catching on threads in the 
carpet and unraveling it.

 

 

b.

  If  mounting  the  anchor  plate 

underneath  the 

carpet

, cut a small flap in the carpet to allow the mount-

ing post to protrude through it.
 

  As described above, use the anchor plate as a tem-

plate, and drill five ¼" holes through the floorboard.

  Next, attach the anchor plate as shown in Figure 

5, using the provided ¼" x 1" hex head bolts and self-
locking flange nuts.

 12.

 

If you find that tightening the flange nut on a bolt 

is  difficult  due  to  a  tube,  channel  or  other  obstruction 
under the floorboard, use one of the provided jack nuts 
to attach the bolt. Refer to Figure 6.

 

  Note: if one or more jack nuts are used, the anchor 

plate cannot be mounted on top of the carpet.

 

  To  attach  a  bolt  with  a  jack  nut,  drill  a  ½"  hole 

through the floorboard at the point you marked in step 
10.

 

 

Note: do not drill out the hole in the anchor plate.

 

  Next, insert the jack nut into the hole (See Figure 

6) and bolt through the anchor plate, using one of the 
¼" x 1" hex head bolts.

 

13.

  This completes the anchor plate installation. You can 

leave  the  air  cylinder  assembly  in  place  —  it  must  be 
attached to install an air line fitting in a later step — or 
you can remove it, if it interferes with the installation. 

  Automatic pedal positioning systems may affect 
the towed vehicle braking system.
  Determine if the vehicle to be towed is equipped 
with pedal presets. Proper connection of the brak-
ing system may be affected by these presets; if the 
vehicle  is  so  equipped,  note  the  original  installed 
position  and  return  to  that  position  before  towing 
the vehicle.
  if the brake pedal is not at the original installed 
position when the vehicle is towed, the pedal clamp 
may apply excessive braking force, which will dam-
age the brake system and/or electrical system, and 
may cause brake or electrical system failure, as well 
as other non-warranty damage.
  failure  to  follow  these  instructions  may  cause 
property damage, personal injury or even death.
