General warnings and cautions

1.

The controller, pulley, cable anchor bracket, cable

housing clamps and the air cylinder are attached with 
self-tapping screws. Before attaching these parts, make 
certain that the screws will not damage any compo-
nents or electronics on the other side.

CAUTION

  Failure to follow these instructions may cause  
non-warranty damage to the vehicle.

2.

Route all wiring to avoid the possibility of a short

circuit or other damage to the vehicle.

  Route all wiring to avoid moving parts, sharp 
edges, the fuel lines or hot components such as 
the engine or exhaust system.

  Use the included wire ties to secure the wiring 
out of the way.
  Wiring exposed by moving parts, sharp edges or 
hot components may cause a short circuit, which 
can result in damage to the vehicle's electrical sys-
tem as well as other, consequential damage.
  Wiring which is attached in close proximity to 
the fuel lines may ignite the fuel.

 

All parts in the interior of the vehicle must be at-

tached so that they will not present an obstruction 
or hazard to the driver of the vehicle or interfere 
with the operation of the vehicle.
  Failure to follow these instructions may cause 
a loss of vehicular control, resulting in property 
damage, personal injury or even death.
