WARNING: DO NOT USE HAND-HELD 2-WAY TRANSCEIVERS INSIDE YOUR VEHICLE WHILE DRIVING.
WHEN TRANSMITTING FROM INSIDE THE CAR, 2-WAY RADIOS THAT OPERATE IN THE 25MHZ-700MHZ
FREQUENCY RANGE WITH MORE THAN 2.0 WATTS OF POWER CAN PRODUCE ELEC-TROMAGNETIC
INTERFERENCE THAT COULD INTERFERE WITH THE OPERATION OF CRUISE AND THROTTLE CONTROLS
RESULTING IN VEHICLE "LIMP-MODE".
USE OF CELLULAR PHONES WILL NOT INTERFERE WITH THESE CONTROLS.
DUE TO SENSITIVE NATURE OF SIGNALS USED FOR THIS PRODUCT, ALL NON-PLUG AND PLAY CONNECTIONS
MUST BE SOLDERED. FAILURE TO COMPLY WITH THIS REQUIREMENT WILL VOID WARRANTY.

Additional Notes
Wiring Information:
The required wiring connections to the vehicle harness are as follows:
Red: Connect to switched 12 volt source. (0V when key-off, 12V when key-on)
Black: Connect to a good ground point on the chassis or firewall.
Orange: Connect to cruise (-) terminal on D.D. systems or your choice of cruise indicators
Blue: Connect to hot side of brake light switch.
Purple: 4K VSS input from VSS output on GM ECUs or Dakota Digital control boxes.
Yellow: Clutch switch Batt input
White: Clutch switch GND input
White/Brown: Connect to cold side of brake light switch. This wire should have 12 volts only when the brake is
depressed. When the brake is not depressed it should be grounding through the brake light bulbs.
If the brake light bulbs are not connected or are burned out, the system will not operate. LED
brake lights will not provide proper grounding. If you have LED brake lights, use an
automotive relay with the white/brown wire between 12 volts and ground as shown below.
**Note** If you have LED taillights in your vehicle you will have to run a relay between the brake switch and the cruise
control box as shown below.
VSS input
If you are inputting an open collector 4kPPM signal into the CRC-2000 you will need to use the provided 1k ohm
resistor located in the red bag. Connect the resistor between the purple VSS wire and a +5V power source. You must
use the provided resistor if you are receiving the VSS from the Dakota Digital “SPD OUT” terminal on a VHX or VFD
series control box. Connect this resistor between “SPD OUT” and “SPD +” on the VHX/VFD control box for the CRC2000 cruise to function correctly.
Control switch:
There are various types of turn signal and dash mount control switches available. The type of control switch that we
supply with the cruise control is a closed circuit type for a turn signal handle control and open circuit for dash mount
switches. If you will be connecting to a factory GM four wire control switch, they are open circuit type. GM switches
which do not have four wires are not compatible with this cruise control. Ford cruise control switches are neither closed
circuit nor open circuit and are not compatible with this cruise control.

Desired Results
Fault Condition
+12V when switched on and +0V when switched off. Ignition
must be greater than +10V while cranking vehicle.
Lowest resistance to ground and closest to zero (0) ohms as
possible. Use a vehicle ground point where other ground
wires are connected to.
Set/Coast: +12V press and hold set.
Accel/Resume: +12V press and hold resume
On/Off:+12V Press On
Negative side of the brake switch: +0V and 0 ohms to ground
when brake is not pressed. +12V when brake is pressed.
No power, voltage drop, or intermittent connection will cause
loss of pedal or ‘Limp-Mode’ condition.
A bad ground connection: Cruise will not function, loss of
pedal function or ‘Limp-Mode’ condition.
Cruise will not set if this connection is not installed correctly.
Cruise will not resume or accel if this connection is not
installed correctly.
Cruise will not set if this connection is not installed correctly.
Cruise will not function if you don’t get desired results. If you
get anything but 0 ohms reading you may need to install the
brake LED resistor.
Cruise will not function if you don’t get desired results. Your
vehicle may have a faulty brake switch, brake relay or fuse.

SAFETY PROCEDURES
This unit is a microprocessor based Cruise Control. It is designed for ease of installation. Carefully follow the
installation procedures in this manual for best results.
DO NOT INSTALL THIS SYSTEM ON A DIESEL POWERED VEHICLE WHICH HAS A MANUAL TRANSMISSION
WITHOUT A DISENGAGEMENT SWITCH (Kit# SEN-4206) ON THE CLUTCH PEDAL ASSEMBLY.
WARNING
Failure to follow the instruction manual could not only cause the system to work improperly, but could cause the
vehicle to go into ‘limp-mode’, possibly causing damage to your vehicle and injury and/or death to you and your
passengers.
Only install on approved applications. The product described in this manual was developed, manufactured and tested

OPERATING INSTRUCTIONS
NOTE**If the cruise indicator (-) is wired, the indicator may light for up to 10 seconds upon power up. This is normal.
ON: To operate the Cruise Control, turn the power button ON. (Green LED Indicator will light, if equipped.) Wait three
(3) seconds before setting speed.
SET SPEED: To engage system, press SET/COAST or press RESUME/ACCEL and release, then remove your foot
from the accelerator pedal. Press accelerator and speed will increase, release accelerator and you will return to set
speed.
COAST: Press and hold the SET/COAST button and your speed will decrease. Release button and speed of vehicle at
time button is released will be new set speed.
ACCEL: Press and hold the RESUME/ACCEL button and your speed will increase. Release button and you will have a
new higher set speed.
TAP-UP: You can gradually increase your speed by quickly pressing and releasing the RESUME/ACCEL button. Each
time you press and release the button your speed will increase by 1 MPH.
TAP-DOWN: You can gradually decrease your speed by quickly pressing and releasing the SET/COAST button. Each
time you press and release the button your speed will decrease by 1 MPH
DISENGAGE: Depress brake pedal slightly; automatic speed control will cease but set speed will stay in the system’s
memory. Also, you can disengage by pressing button to OFF position, but this erases the memory. To get the RESUME
feature to work again, you must first set a speed. Turning OFF the ignition also clears the systems memory.
RESUME: After disengaging system with brake or clutch, press RESUME/ACCEL button and release it. If acceleration
rate is faster or slower than you like, drive to within a few MPH of your set speed, then press and release the
RESUME/ACCEL button.
About Dakota Digital Cruise Control
The performance of the Cruise Control is dependent upon the condition of the engine, its size and even by the type of
emission control equipment it has. Driving at higher altitudes will have an effect on Cruise Control’s performance.
Under normal conditions, speed should be controlled within plus or minus 1 MPH. There may be situations; however,
which make it seem as if the Cruise Control is not capable of functioning accurately, such as an extra heavy load, a
very steep hill, or a severe headwind.
CAUTION: Do not use the Cruise Control on a slippery road or in heavy traffic.
CAUTION: (Manual Transmission) While driving with the Cruise Control ON, do not shift to neutral without depressing
the clutch pedal, as this may cause engine to over-rev. If this happens, depress the clutch pedal or turn OFF the main
Cruise Control Switch immediately.
