Instruction manual

If the Red LED inside the servo is continuously lit when you to turn the 
vehicle key on, try removing the purple wire from the circuit. If the  
Red LED inside the servo shuts off, either the brake lights are stuck on and 
you need to readjust the brake switch or you need to use a SPDT relay in 
the brake circuit. 
If you already have a SPDT relay in the brake circuit, either you have the 
wrong relay or you have it connected wrong. 
Throttle connection Test: 
The cruise control will shut its self off if the vehicle speed drops over 10 
MPH below Set speed. If you have too much slack in the Servo cable, the 
cable has to move too far and will shut its self off. 
You want just a little slack at idle in the cruise control servo cable (closed 
throttle position) but you must have enough slack that the throttle is fully 
closed. This is a trial and error process. Too much slack and the cruise will 
be slow to respond. Way too much slack and the cruise may not respond at 
all and the chance of the bead chain hanging on something increases 
Grab onto the cruise control servo cable with a pair of pliers and pull on it. 
If you can’t open the throttle relatively easily the cruise control won’t work.  
Try a different position for the cruise control servo cable until you find one 
that you can open the throttle easily. 
Cruise works but drops too much speed before it kicks in 
Only two possible reasons for this: 
Too much slack in the servo cable (See Throttle Connection Test above) 
You need to increase Sensitivity Settings on the DIP switches. 
The original CCS-100 instructions call the Sensitivity Settings Low, Medium 
and High. They really should be called Slow (Low), Normal (Medium) and 
Fast (High). The faster the sensitivity, the less the speed drops. 
Cruise works but drops too much speed going up hills 
Same two possible reasons for this: 
Too much slack in the servo cable ( See Throttle Connection Test above)
