DIY Cruise Control on 07-08 Yaris (step by step)

[Sodium Duck]

Works great! Thanks to all who put this DIY together.

The cockpit:
Cruise controls to my left.
CB, aftermarket stereo, 2009 black knurled control knobs, Ecometer and painted flat black trim to my right.

I love my Yaris.

If anyone wants my leftover resistors, I'll mail them to you, just PM me. I have 4 (comes in a pack of five).

Resistors are gone.

2008 HB 3 Door Yaris Qustion

How much of the dash do you have to remove to see these connectors? Are some of them under the hood?

Thanks

I don't believe so. The way to test if it might is to measure the voltage on pin 40 of the ECM connector A21 (the pin where the cruise switch connects to). If that pin measures 12 V with the ignition on, then it might work. If it doesn't, then your ECM doesn't have the cruise control functionality built in.

thanks scott..will try and measure..if it does have, i can do the wiring as stated.?..will the indicator shows at the meter panel?..

If it does have it, then you can do the wiring as above. For the indicator, you can shine a flashlight on the panel to see what indicators are there, and if the cruise ones are.

hi scott,

i see this post on opening the ECM. If i dc the battery, how do i measure the 12V?

very very sorry for asking a noob question...i have a DVM with me but dunno which wire/connector i need to measure to make sure my car having cruise control function...hope can get some help ...thanks..

To take the measurement you would need to do so with the battery still connected and the ignition in the on position. For actually doing the wiring I suggest that people disconnect the battery, while doing so.

You can stick a pin through the rubber plug in that pin location of the ECM connector to take the measurement.

Based on others experience, I don't believe that your car's ECM will have the cruise control functionality.

If I got the Toyota Stalk from ebay, do I just wire it directly to the ECU or does it need the resistors as well?

Directly to the ECM. The resistors emulate what is inside of the stalk.

I don't believe that your Yaris will have the cruise control functionality, as thus far it seems to only be US and Canada Yaris that do. To check before talking your steering wheel apart, measure the voltage on the ECM pin with the ignition on. If the pin doesn't measure 12V, then the stalk won't work.

Hey guys, I need help! I just spent the afternoon putting in the two-button diy cruise with CTScott's indicator module...seemed like the install went pretty smooth, but it's not working! When I start the car, the indicator light goes on, then off for a quick moment, and then stays on. What could that mean?

I used two buttons (the black radio shack ones) and three 220 Ohm, 1/4 watt resistors in series, for 660 Ohm...should be right in the range, yes?

My first thought is that it is the ECM connection. I ordered the original factory part, Toyota repair terminal, or whatever it's called, and I had a heck of a time putting that thing in. My main problem is that it was a square peg going into a square hole, but first going through a round hole....It was very difficult to line up, and I gently played with it until I got the most secure fit I could, but I'm still not convinced it's in all the way.

Any thoughts?

The light staying on indicates that the indicator module is seeing the switch wire being shorted to ground.

For getting the pin in, did you pop the orange thing on the side of the connector, which is the retainer for the pins?

[Falconeer]

CTScott.. I am aware of that and was planning on checking that soon. I have a rental Yaris I can experiment on at the moment!!
Mine gets delivered on the 24th.

Have all the parts to do a 2 button cruise on a 08 Yaris HB MT. Couple of questions/confidence builder...

What kind of connector are you using for the clutch control switch wires were they are connected in the fuse box?

Getting the wires through the firewall seems like the biggest challenge.

Where is the grommet on the passenger side, what color is it, any information of what you have to remove to see this grommet would be extremely helpful.

The hood release method, what do you have to remove to go that route? The plastic in the wheel well, does that need to be removed?

Do you wrap these wires in electrical tape?

I'm a real rookie at this, any tips would be greatly appreciated.

Thanks,

Rich

"Where is the grommet on the passenger side, what color is it, any information of what you have to remove to see this grommet would be extremely helpful."

This was so annoying for me. I found it easiest to go under the hood and get it from there. Look at the ECU, the grommet is to the right. It's black, like an inch or so wide. I popped mine out, and pushed a sharp piece of metal at the carpet behind. Then I went back in the car, saw where the metal was and cut an X in it. Ran the wire through and was done. I don't know why it took so long...
