[ THIS MANUAL, YOUR KIT AND YOu-~

This Cruise Control Kit is a microprocessor based Cruise Control. It is designed for ease of
installation and can be used with most cars, light trucks and vans. Carefully follow the installation
procedures in this manual for best results.

DO NOT INSTALL THIS SYSTEM ON A DIESEL POWERED VEmCLE WmCH

HAS A MANUAL TRANSMISSION WITHOUT A DISENGAGEMENT

SWITCH (250-4206) ON THE CLUTCH PEDAL ASSEMBLY

Your vehicle must have a VSS (Vehicle Speed Sensor) wire or an available signal generator for
installation of this Cruise Control. Please consult vendor's Application Guide.
Low displacement engines with limited vacuum will get better performance if a vacuum reservoir
is installed. Vacuum reservoirs, pumps, regulators and other accessories are available from your
dealer, automotive service center or most automotive parts outlets.

All through the instructions there are W ARNINGS, CAUTIONS, AND NOTES that are meant
to make it easier for you to put the Cruise Control on your vehicle and safer to use. We have
gathered these tips from people across the country who have told us about their problems and

how they worked them out. Even with all these reports from the field, we cannot cover every
condition which you might encounter, there are just too many different vehicle makes and models.

We do our best to tell you how to handle most vehicles, but we must Denend On Your Good
Judgment for dealing with the rest.

Therefore, we believe you can understand why we strongly urge you to think carefully about
what could happen to you, your passengers and your vehicle if you use any tools, parts, fastening

methods, routing or procedures which are not described in this manual.

There is NO drain on the battery if the control switch is left on. The Cruise Control needs no
regular service.
