Your Canadian sedan may not have the wiring from the ECM to the steering column, and if that is the case you would need to add the ECM pin.

This thread has a DIY with more details:

ok cool thanks for the info!, so D3 connector is left side of the yellow connector ? and if there is a blue wire there, then i can just tap into it, if not i have to run a wire through the firewall to the ecm?

Correct on both.

great news, i just checked and i have all 3 wires, and my dash cluster has the set and CC indicators.

do i have to use the switches you mentioned, or can i use a plain SPST Normally open pushbutton that i can buy from my local electronics store?

Any normally open switches are fine.

people are telling me if i dont use the expensive "aftermarket cruise control kit" which is like 3-500$ with installation that the CC might not disengage or the insurance company wont cover if something happens cuz its a DIY modification

, are there any risks involved in using this mod? also i got a single 620ohm 1% 1/2Watt resistor, (im using 2 switch method) is that enough?

Cruise control is a function of the ECM. You are just enabling that existing functionality by adding the switches and resistors as an input the ECM. The only way it can "not disengage" is if the ECM fails.

The aftermarket Rostra kit was actually recalled, because it has an issue where RF noise can make it misbehave, so I'd stick with enabling the OEM functionality.

ok, thanks for the advice, all i have to do now is find out where to mount these buttons

, ive decided to just use utility knife to strip away the insulation on the 2 d3 wires and solder them in, i want the best connection possible so soldering is the way to go. i will post up my results once i have finished this project, thanks for the help ctscott!

09sedan · 02-23-2012, 09:05 PM

just finished the wiring OMG IT WORKS !!! GREAT SUCCESS!!

THANK YOU CTSCOTT!! you just saved me almost 500$ !!!

if you ever come to toronto, let me know i owe u a few beers

Hi Scott,

If I don't have cruise control in Yaris 2008 EECU ( In NZ ) can I change US market ECU and will it start as normal ? Then can I do my DIY CC ?
Cheers.

Ive had my Yaris World cc for maybe two years now. I drove a friends car with stalk cc and HATED it. My four button cc is SO much easier to use!

Question: one button is on/off, another button is set/decel, and button is resume/accel.

What is the fourth button?

Possibly, if you have the 1NZ-FE engine. I believe that your cars follow the JDM Vitz wiring. I have not done a pin for pin comparison of the US versus JDM ECMs to see if any pins need to be moved around.

chanka · 09-08-2012, 03:47 AM

Thanks Scott, If its hard I'll go for this option.

You do realize that that device is not cruise control, but rather a device that makes the throttle seem more responsive?

chanka · 09-10-2012, 02:11 AM

Yes I noticed that now. I'm still looking for a CC that I can fit externally.
Cheers SCott...

I have the 2009 automatic with OEM cruise control and the stalk annoys me and frustrates my wife even more. We loved the OEM flick stalk on the old Camry!

Could I tap into the wiring and add this even though I have the OEM stalk? Essentially I'd have two sets of cruise control controls... control controls lols

I can't see why I can't do it this way, but I don't want to poke it and end up with no cruise control.

I'd like to add a set of buttons or a joystick somewhere, but leave the OEM stalk in place so when it comes time to sell the car on I can take the secondary buttons out so as to not confuse anyone.

Can you post a picture of your OEM stalk? I am wondering if your Australian CC is different (and perhaps actually an aftermarket system).

If it is actually the OEM type used on the US Yaris, then you can indeed add the extra set of controls by tapping the two wires.

azeeroth · 09-11-2012, 07:11 AM

I've had the steering wheel cover off to do the headlight relay mod, and from memory there's just one thick black cable going to this stalk. Presumably that goes back to the same wires you've described though.

Oh yes, this was done by the Toyota dealer before we got the car, so it's as factory as they do it here. I remember asking about the Camry style flick switch and they said something about not being able to do that as factory and they'd have to "put the cruise control in afterwards" so it could be an aftermarket one that Toyota uses.
