Why Cruise Control in a Grand Vitara that is 10+ years old?
Simple Answer: Just because it can be done and has been done by several people, in countries, where the Vitara came without the Cruise option.

How do you know if the vehicle is cruise ready?
If the vehicle has the fuse for cruise in the fuse box (under the steering/driver side footwell area fuse box), you are in luck and have a cruise ready vehicle. It's just that the cruise control buttons have not been put in that model of the vehicle.

Can Cruise Control be installed on Indian Grand Vitara?
Yes, on both the 2.0 & 2.4 versions.

What are the parts needed?
This below diagram served as my reference guide for parts and connections.


Different types of Cruise Control switches


The cruise buttons are of different types with different part numbers and after much reading, on Russian online forums, understood that there were different cruise control buttons for models with backlit & non-backlit options. In addition, there is also a combi-type part that has both Audio & Cruise controls but the connector (G54) in that is of a different type and I was almost 100% sure that our Indian Vitara did not have that connector inside. You can go down that route but will need to change more parts and will be very expensive.

So, the combi-type was out of way and the choice was to either order backlit one or non-backlit one. This was made easy by the following considerations:

• The non-backlit one was cheaper and available easily (for me)
• Less wire connections/cutting/joining and more straight forward install

The only drawback would be loss of backlight on both the audio & cruise control switches, on the steering wheel, when lights are turned on.

The SGP part#37460-64j40-zcp arrived in couple of days:


This is the cruise module:


The wiring on the connector side. Non-backlit one has 4 wires (discount the blue wire) and the backlit version would have 6 wires (2 extra for backlit)


De-pin the wires from the connector and this is how it looks:


NOTE: De-pinning is not a straight forward task of just pulling the wires from the connectors. The connector has locks and wires/pins have to be removed carefully, else the pins will break.

[khan_sultan]

Took the vehicle to a service center and got the master electrician to do the connections. I told him which wire goes where, what to do and he followed the instructions blindly:


Preparations to remove the steering and airbag (Remove the plastic panels below the steering also):




Behind the steering you will find this connector (G33) which has the audio control wires. Make a note of the colors of the wires and the slots numbers (green-empty-black-red-orange-pink)


Remove the orange & pink wires/pins from the connector. (Any good electrician will know how to do this cleanly, so, will not describe this in detail)


Orange & pink wires removed (these are the wires for the audio backlit connection)


This is how the steering will look after de-pinning the orange & pink wires from the G33 connector

[khan_sultan]

Remove few cms of the black sleeve to open up the wires and then cut the orange & pink wires. Remember to insulate the cut ends individually.


Make sure to keep the pin & the cut wire safely. These will be used later:


Now, remove the steering completely and then screw on the cruise control buttons. Remember to take the wires behind the wheel, in same manner as the audio wire bunch, so that when you put it back, the bunch of wires do not obstruct the airbag:


The most important part of making the connections:

• Grey wire from cruise goes to the slot from where pink wire was removed.
• Yellow wire from cruise goes to the slot from where orange wire was removed.
• Brown wire from cruise goes to the empty slot of the connector.
• Splice (Do NOT cut) the Green wire in G33 at the connector end. Cut the Green wire from cruise, leaving few inches of wire with the pin (Keep the wire-pin safely) and connect the Green wire from cruise to the spliced portion of the Green wire in audio block/G33 connector

This is how it will look:

[khan_sultan]

Underneath the steering you will see two connectors -- Yellow & White. The white one is the other end of the G33 connector we have worked on till now. Remove it and you will see 5 wires in it:


The 5 wires & an empty slot. The 2 wires on the extreme left, the red-blue & the red-yellow ones, and the empty slot are of our interest.


Cut the red-blue & the red-yellow wires. Remove the locks from the connector and insert the pin from the blue wire (extra wire left from cruse control) into the empty slot. Cut the clamp end of the blue wire. This is how it will look:


Now find 3 wires of approx. 1 mtr length each (you can find in service center easily and they will be of automotive grade, same/similar spec)


This is how the car looks at this point of the installation:

[khan_sultan]

Connect the 3 wires to the wires in the G33 connector (Remember the color of the wires & their slot position):


Connect these left over pins to the other end of the wire. (incase you need a pin, you can source it from the waste wiring harnesses etc. Just ensure it is of correct type and will fit in the connector):


Under the drive foot well you will have to find a grey color connector. (G05 connector) It will be just below-side of the fuse box. Remove the lock from the connector, so that wires can be added to it:


Bottom row, the 3rd, 4th & 5th slots from left are empty and are the slots where we need to connect the wires. We will call these slots -- slot#12, slot#13 & slot#14 respectively

• The pin at other end of the wire which was put in empty slot in G33 will be inserted into slot#12 of G05 connector
• The pin at other end of the red-yellow wire will be inserted into slot#13 of G05 connector
• The pin at other end of the red-blue wire will be inserted into slot#14 of G05 connector

This is how it will look:

[khan_sultan]

That's it! Now put everything back in reverse order carefully. This is how the steering would look:


Press the MAIN button on the cruise control switch and the CRUISE light on speedo should show up.


Have tested the cruise for approx. 50 odd kms till now and it works perfectly. Setting speed, resume from memory, speed increase/reduce, cancel from button and if you use the clutch/brake/change gear, work perfectly fine.

NOTE: The cruise works only in the 4th & 5th gears at speed of 40+. The cruise does not work in 1/2/3 gears and I don't know the reason (this has been reported in Russian forums also and I knew it before hand and is not something I found out after install).

The cruise works as described in this link: https://monolith.in.ua/kruiz-kontrol...-grand-vitara/

Summary (In case this link does not work in future)

It's important that I share the resources I used as reference for this install.

While there were several international forums where installation of cruise was asked/discussed, the first detailed tutorial I found was here and the OP here had created a tutorial shared here. This was in Spanish and I even got the tutorial converted into English for better understanding.

This led me to the discovery of Russian forum threads where there are dozens and dozens of thread on this topic of Cruise Control on Grand Vitara. I read & re-read them all (almost all) and took me some time to understand terms like dorestyle, restyle, used on the Russian forum, and what they meant in context of cruise install. It took lots of time to understand different wire colors and what each wire does in audio side, cruise side and different connectors. Got several circuit diagrams translated from Russian into English using google translate & and then finalized on how to approach it here.

For example:

A truly worthy update.

Cruise in my Brezza works only above 40kmph in 3rd, 4th and 5th gears. No idea why.

Maruti/Suzuki also has ample playground available in their cars. I've read about a few users installing cruise control in their VDi and ZDi variants of Brezza.

[Ashtoncastelino]

Excellent work ! A much deserving feature missing in the GV installed nicely ! Congratulations

Although small suggestion from my side, better to use heat shrink tubes than electrical tapes as over time they get sticky and messy.

Always wondered why Maruti had skipped this feature if the electricals supported it ? Glad you found out the solution.

Many thanks for sharing. I too am studying upon installing cruise control on my Uncle's Brezza ZDi AMT. Though it will be complex, It would help my uncle a lot since he goes on frequent Long drives.

Thanks for the detailed steps in getting this done, this similar process is used till date in installing steering mounted controls by Karol Bagh shops till date, glad to know they are doing it right, namely installing the controls, replacing the coil to newer one with more pins or something (MGP), taking out extra wires using pins to the audio system and assembling all that.

Great job, thanks for sharing!

It is interesting that all the components for the cruise control are already installed, except the buttons. It’s a bit more than just some wiring. There are several (micro) switches on the brake and clutch pedal (if MT) and there needs to be some sort of actuator mechanism to control the throttle.

Just a word of caution for anybody doing this DIY: Make sure you disconnect the battery before attempting this job, in particular removing the air bag. Your car battery needs to be disconnected for at least 10-15 minutes before removing the air bag, or it might get triggered when you remove it!!

Fully agree. Heat shrink tubes would be better!

Yes, except the switch/wiring, all the components needed for the cruise are already present. That baffles one more as and wonders why would manufacturers not remove those from non-cruise models and only remove the external control interface. Maybe the cost to remove internals would be more and more cost effective to keep them hidden and remove only the external interface.

Yes, I asked the electrician about it and he just said -- "Don't worry, I know how to remove it without disconnecting battery wires". I was skeptical but had no choice but to trust him on that. However, I would say that better to remove battery before and then do this.

An Amazing DIY Job, Excellent Work!

Cruise control is a boon in Highways these days.

Installing cruise control in Suzuki and Hyundai cars are pretty easy IMO. In VAGs one have to perform all sorts of Gymnastics and Yoga to access the BCM and the ECU.

Obviously so they can squeeze us for more money for the "higher variant".
