STEP I. HA TTERY DISCONNECT:
Ifvehicle is equipped with Anti-Theft Radio, record security code before disconnecting battery cable.
Il"eter to vehicle,9wners ,manual for instructions. Raise vehicle hood and remove NEGATIVE battery
, , ,
cable (See FibYilreC).
STEP 2. Receiver Module Installation:
Remove existing Cruise Control Switch, if one exists. Refer tp Ifelpful Hint #2 to when disconnecting
4 pin connector.
Choose a location under the driver's side dash to mount the receiver module. This location should be
chosen such that interfacing to the existing cruise control harness does not cause stress on the wiring
harness. It is best to leave at least 2 inches of slack in the wiring harness once it is connected. Also, for
best performance, choose the location such that there is no significant metal (excluding wires) in the
line of sight to the steering wheel. .
Mount the receiver module in the location chosen using either tie straps supplied, or the bracket
supplied.

Secure the supplied transmitter mounting bracket to the steering wheel as indicated by the mounting
"
bracket installation note.
Slide the transmitter on to the mounting bracket. Firmly press the transmitter on the bracket until it
locks into place. The bracket has automatic locking pins to secure the transmitter.

TROUBLE SHOOTING GUIDE FOR CRUISE CONTROL WITH
REMOTE CONTROLLED SWITCH
TRANSMITTER
(mounted on steering wheel} RECEIVER
(mounted under dash)
Equipment Needed
I) Volt/Ohm meter
2) Jumper Wire
~ eory o Remote Controlled Switch Operation
The ROSTRA remotecontrolled cruise switch incorporates the samefeatures and functions as contemporary cruise control
switches plus a few enhancements.The primary functions; SET, COAST, TAP DOWN, RESUME, ACCEL, and TAP UP
operateno different than any other cruise switch. However, the medium of communications from the switch to the cruise
control is now Radio Frequencyasopposedto wire. The benefits of the remote controlled switch are numerous and include;
ability for in-wheel switching witl1out interference of airbags and other critical components of the steering wheel assemblyand
simplified installation.
Electrical Tests
Electrical tests are perfonned on the 8 wires at the cruise control module. Using a Volt/Ohm meter, conduct the following
fl'c;ts where the wiring harness enters the cruise control module. The diagram below illustrates the wire locations, colors, and
lunctions on the wirillg harness entering lIl(; cruise colllrol module.

Entering Diagnostics Mode:
I. Turn the Cl1lise Control Switch to tile OFF position
2. Turn the ignition switch to the OFF position
1. Turn the ignition switch to the ON position .vithout starting the engine, hold the RESUME/ACCEL button
down while you turn the Cl1lise Control Switch to the ON position.)
4. The Diagnostics LED should be off at this time.

I I. Install the new transmitter or receiver as described in the manual attached.
2. Use Volt/Ohmmeter to verify the steps you are about to make.
I 3. Connect the Volt/Ohmmeter to the Jrd pin from the left (next to Orange wire) on the lO-pin connector
of the interface harness.
4. Turn the ignition power on, without starting the engine.! 5: The Volt/Ohmmeter should read (+5 volts ).
6 Locate the Orange wire with the Tee-Tap on the interface harness.
7. Using the jumper harness, momentarily ground the Orange wire.
8. The Volt/Ohmmeter should read (0.0 volts).
9, Using the jumper harness, momentarily ground the Orange wire again.
10; The Volt/Ohmmeter should read (+5 volts).
11. Momentarily press the SET button on the transmitter.
12 The \!olt/Ohmmeter should read (0.0 volts)
13. Momentarily press the SET button on the transmitter again.
"; 14 The Volt/Ohmmeter should oscillate from 0 to +5 volts for approximately 4 seconds indicating the
., programming was successful.
-15 The remote controlled cruise switch is now ready for use.
NOTE: At step 14, if the Volt/Ohmmeter didn't oscillate, but stays at (+5 volts) for 1 second, then stays
at (0.Ovolts ), then the programming was unsuccessful. Turn the ignition power off and repeat steps 1-15
above. ,
CAUTION: Be sureto road testyour Cruise Control after installation. If your Cruise Control was installed correctly, it
should perform asindicated in this section. The Cruise Control Switch is usedto operate the system.
Do not useCruise Control on slippery roadsor in heavy traffic.CAUTION:
