Hopefully I can help. The first question is if the ECM on your Yaris has the cruise control function built in. If you could PM me the VIN number of your car, I can run it through the international EPC to see if it does.

Where can I contact you to get the spare parts. From which model can I bought it? Please help? Danie from South Africa.

I PMed you back regarding some additional information that I will need to determine if the ECM on your Yaris has the cruise control function built in.

I'm still looking for someone around the Connecticut area that is interested in having cruise control installed on their 2012 Yaris.

I shipped a stalk to a gentleman from South Africa, who successfully installed it on his Yaris, but he had a tough time with figuring out how to remove the airbag. I believe that from the pictures that he sent me, that I now have a good grasp of how to do so, but I would like to get it documented to make it easy for anyone who wants to DIY cruise control to do so.

Scott; do you think the clockspring from the 2012's would work in the previous generation? I would love to have cruise and audio controls.

My bet is that it will fit and it does have the extra wires necessary to allow for both cruise and steering wheel controls.

I guess I'll have to order one and see if it indeed does.

I shot a few photos showing the pins and how to access them to remove the air bag/horn button. Just a note - I turned the steering wheel for easier access to the pins (thus photos show upside down). I never diconnected the airbag as it will rest on the steering wheel and allow easy access to install the stalk and connections.

Thank You! Those pictures help dramatically in understanding the process and the method for accessing the pins! I got mine in the mail earlier today and will let everyone know how it goes! :)

EDIT: Ok, just went and installed mine on my 2012 Yaris L. VERY EASY. Bad news: It doesn't work. The Green light comes on, however, it will not set at a speed. I have a distinct feeling that the clutch switch is not on the 2012 Yaris L... I looked under the dash and did not see a switch, except for the starter safety switch; there was only a bolt to stop the clutch from coming up.

EDIT 2: Ok, I have confirmed that my 2012 Yaris L (3-door) does NOT have the cruise control clutch switch. All of the wiring is there (including the harness connector) but the actual switch is absent. I was able to jump the pins on the connector (THanks CTScott!) and the cruise worked fine. So, if anybody is adding cruise control to their 2012 Yaris L (Manual Tranny, of course), it looks like we will need to install the clutch switch. (Hey, at least all the wiring is there! :-) )

Also turned the wheel upside down for better access


3 Clips














Here is under the dash where the "clutch switch" should be

Thanks for all of the pictures gentlemen! This will now allow me to put together a proper step by step DIY for the 2012.

Thanks CTScott,

The pics of the airbag clips made it super simple!!! I only had one real problems and that was removal/install of the horn pin on the old 4 pin connector... I broke it!!! I tried to force it!!! It's ALL MY OWN FAULT!!!! The removing the pin was almost impossible as there isn't a pin unlock like anything in the picture...

Well except for not having a horn, it works great on my 2012 3dr L 5spd

Also the lower dash panel under the steering wheel has an airbag, so that meant getting down on the ground and contorting myself to look under but the clutch switch was really easy to instal. The biggest bear was trying to pull off the tape from the harness to drop the connection for the clutch switch...

I just got back from the test drive and a refill... So 2 tanks and I am averaging 41.6 mpg I am pleased as I am still running 32psi in the tires and running A/C!!!

I am sure the CC will make the commute more tolerable... The aero hubcaps are enroute... And the next upgrade will be the speakers...

I apologize for the broken pin issue. For 2006-2011 Yaris I ship the harness with the horn wire installed. After the last couple of 2012 installs I didn't think that I needed to include it, as the horn wire was on the other connector, but as it turns out that is only for 2012's with steering wheel audio controls. For ones without the horn wire is still on the 4 pin connector where the cruise control connects through.

Scott,
I am happier than a pig in poop!!! I should have been able to do it, but these Yota pins are unlike many of the pins I've messed with... It looked simple, but I am sure there's a trick to em...

Ordered the parts from CTScott, got them quickly.

The install was relatively simple. It took me about 15 minutes. Everything works perfectly.

Thanks CTScott!!!!

Also ordered from CTScott and got the parts in UK very quickly and no customs issues (despite USPS tracking saying the package is still in USA!)

I notice my steering wheel assembly is slightly different from Richard_RSP's (but thank you for the pictures that helped a lot in knowing what I was aiming for.

I have the steering wheel audio and also the bluetooth telephone control on my UK Spec 2012, 1.33 Yaris TR Auto (not sure which bit of that means I have the different clips though!)

Also, pin 1 & 2 of the 10-pin connector are already occupied so I put the cruise in the spare 4-pin socket next to it.

Edit- It works!

[CTScott]

Excellent! I am glad to see that the installation went well.

Correct - According the the wiring diagrams for the European Yaris, only the Yaris with the 1NR-FE (1.33L) support OEM cruise control. Ones with the D4D would need an aftermarket cruise control solution.
