CTScott, how can I get one of those ECM terminal pins?

PMed with payment info. I have the pins available.

I've used the CTScott cruise control system and procedure. works great. I have little experience working on cars. successful install.

oh but i should mention you'll need a variety of butt splices and extra wire ... i wish i could remember the gauges but its all around 16 to 22. depening on what wire you use to ground you might need a different gauge lug for that too.

I am from Egypt (middle east). I have seen this DIY years ago but never had the guts to do it. I am a noob when it comes to car mechanics and also afraid of electronics :D. I don't know if my car has cruise function. To summarize, I need to check if PIN 40 has 12 volts when ignition on. Wish me luck everybody. I hope that the car has the function so I can do it, my 300 kms daily route to work would be so much better. I think that toyota must have installed it in all the cars not specific to a certain segment. When I first bought the car it had no rear speakers and when I bought the speakers and during installation, I found out that all the wiring is done and all I have to do it place the speakers and that was it. Do I need to remove the steering wheel to get to the D3 connector??? :d

Unfortunately your Yaris does not support the OEM cruise control. For 06-11 Yaris, only US/Canada ones with the 1.5L engine have it built into the ECM.

I really wished I have it. So just for my own curiouisity which one is the D3 connector where is it exactly

It is on the bottom of the steering column. My complete DIY shows how to get to it:

Since this thread is revived, I have to say, It worked on my 2007 Sedan (Canada)!! Started out with no tool, I spend ~$15 on it. Compare to, let say, OEM Cruise from dealership its almost nothing. Thanks CTScott for the awesome DIY writeup and everyone's help.

Now I need to work on making aesthetically look good.

Thanks guys for the detailed instructions for the cruise control installation for my '07 \yaris. It works awesome. J&T

Hi All

I tried this today on my December 2006 YR. Is there a way to tell if you've made a connection to pin40 on A21? Is there a test resistance to ground or another pin for example?

Mine also does not have the blue wire populated in the fuse box for the clutch switch either. Does this mean it's a no go? There is a pin at the bottom (just not a wire coming out of the plug), which I tried grounding, but couldn't get CC to work.

Thoughts any of you gurus? :)

For the pin 40 test, measure the voltage on the wire with the ignition switch in the on position. You should see 12 V on that pin.

The missing blue clutch switch wire is potentially a bad sign. Did you verify that there was not a connector taped to the harness, just above the clutch pedal?

Thanks Scott

Will check pin potential - didn't look for connector at the time, but I don't have one.

Is the clutch switch required? Is it's purpose to disengage the cruise when the clutch is pressed in?

The clutch switch is required for MT cars. The switch works the opposite of the clutch start switch, which is why it is a separate switch. It does disable CC when the clutch is touched, to prevent revving.

Thanks for the quick reply. My dad wants cruise in his 07 MT LB yaris. I'll get the part ordered.

I stock all of the cruise control parts at less than dealer or mail order prices, if you need anything.

I installed CC on my 09 Yaris in the summer of 09 according to CT Scotts instructions. It has worked flawlessly ever since.

I work building electronic devices for space and military applications. I told my supervisor about the CC mod in my Yaris and he looked alarmed.

"Paul, I cant BELIEVE you are modifying your brand new car by what some idiot on the internet is telling people to do!"

I also just finished installing the CC mod on my '09 Yaris according to CTScott's instructions 2 days ago. I am still baffled by how easy it was to enable this function.
Before, when I went to a dealership to ask if they could do it, they said they didn't even want to touch it.
"If it didn't come with it originally, we can't do anything about it." I would love to go back there now and just laugh at their faces.
I'll post some photos once I label all the buttons.

Thanks again CTScott! You are trully a Yaris mod master!
