actuator switch.

Air conditioning and auxiliary belt-driven equipment installation recommendations:
No alterations or additions to the accessory drive belt system will be warranted on serpentine belt systems.
The serpentine belt type of drive is designed as a total system, incorporating a single poly-V belt and an automatic tensioner. In this type of
system, degrees of pulley wrap, belt tension, and pulley alignment are very critical factors. Modification is not recommended.
In some single belt serpentine systems, belt tension is determined by the automatic tensioner and its position relative to the belt. No
adjustment is required.
Due to the critical nature of the accelerator system, anyone making modifications or alterations assumes complete responsibility for system
reliability, performance and compliance to FMVSS 124. Caution must be exercised so that the accelerator cable is properly routed.
Specifications are as follows:
• Route cable to maximize all bend radii. In no case should bend radii be less than 3 in. (76 mm).
• Minimum distance from exhaust manifold to be 6.0 in. (150 mm), unless a heat shield is provided.
• Do not use accelerator cable or clips to route wires, harnesses or other cables. Cable sheath must be clipped so as not to pinch
inner cable. Cable must not be loose in clip allowing sheath to move when accelerator pedal is applied and released.
• Cable must not be subjected to kinking or routing across any sharp edges.
• Cable routing must be perpendicular to the surface of the front-of-dash at the dash fitting. No objects or routings should force
cable to have a bend at the dash fitting. Flexible components (hoses, wires, conduits, etc.) must not be routed within 2.0 in.
(50 mm) of moving parts or accelerator linkage unless routing is positively controlled.
