Familiarize yourself with the Installation Instructions and Cruise Control components.

A. Wllen disconnecting connectors, hold connector and ress the lock downward while pulling connectors apart.

B. When connecting mating connectors, push connectors together until locking mechanisms are

fim11y locked together. (Figure B)

If vehicle is equipped with an Anti-Theft Radio, the radio codemusfbe written down prior to

discolmecting battery cable. The code must be reentered when the negative battery cable is reinstalled.

Remove the vehicle's battery terminals before

installing the Cruise Control components

for safety precautions. (Figure C)

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 FibYilre C).

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.

:~1;;:~:[~'

STEP 3. Mounting the Transmitter:

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.

£ The RF transmitter I~ a NORMALLY OPEN SWITCH. It is necessary to adjust the programming switch

;; on the Cruise Control (where applicable) to the correct position. Refer to your Cruise Control

, Installation Instruction Page #7 for normally open switch.

~ eory o Remote Controlled Switch Operation

The ROSTRA remote controlled cruise switch incorporates the same features and functions as contemporary cruise control

switches plus a few enhancements. The primary functions; SET, COAST, TAP DOWN, RESUME, ACCEL, and TAP UP

operate no different than any other cruise switch. However, the medium of communications from the switch to the cruise

control is now Radio Frequency as opposed to 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 assembly and

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.

Mechllnical Tests

Veri(v the cruise cable and linkage is properly installed by visually inspecting all related parts of the throttle connection

Verify that the cruise control cable is free to operate from obstruction or resistance. Verify that all brackets are secured

properly and not damaged. Replace any damaged parts. , c

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. O volts ), then the programming was unsuccessful. Turn the ignition power off and repeat steps 1 -15

above. ,

CAUTION: Be sure to road test your Cruise Control after installation. If your Cruise Control was installed correctly, it

should perform as indicated in this section. The Cruise Control Switch is used to operate the system.

Do not use Cruise Control on slippery roads or in heavy traffic.CAUTION:

w ARNING

When conneetmg this system to the vehicle, ensure that you follow this instruction manual and connect only to

spccifi~ wires. Failure to do this may cause the cruise control switch to work improperly, cause electrical or engine

failure. and may result in damage to the vehicle and/or injury to the occupants. We must depend on your skill and

good judgment as you install this system. We urge you evef). step of the way to consider the safety of yourself, the

f owner of the vehicle, and those who ride in it.
