I think that is the problem the pin is not there on that side.

If that is the case, you'd need to follow the procedure on the first page for the 2008 or older Yaris to add the pin, and then run the wire from it to the blue wire. The brown should be fine, as that one is just a ground.

Ok, but where does the blue wire from the switch should lead? They just cut it on the middle from the cabin to the ECM?

The wire goes from the ECM to a junction connector that is way up under the left corner of the dash. From there a second wire goes from the junction connector to the connector under the steering wheel.

I will be running that wire tomorrow morning then, Do I need the special connector listed for adding the connection to the ECM or could I tested just passing the cable through the space where it goes on the black plug that goes to the ecm?
Do a regular cable connector works? ( the little square ones)
Thanks for your help!!!

You definitely want to get one of the real pins for permanent installation, but you can try the "shove a wire in" method for testing. I wouldn't try any other type of pin, as if it gets stuck you'll have a real mess.

[magnum23]

Thanks for your real fast reply, I will try the wire method tomorrow, and order the special pin from the local dealer tomorrow. I will post if it works.

Update:

I did the wiring, but the cruise control icon is not showing up in the cluster, but I did what you told before, to measure the volt, and now is getting the 12 volt, and when I press the On/Off bottom on the stalk the volt drop to 0.1

Now that you are seeing the correct voltage, have you tried it on the road to see if it works (even though the cluster doesn't light)? If that works, then check the part number on the back of your cluster.

Ok, I did a road test and is working, but for some reason is not showing it on the cluster, and it have the light for it, the cluster part number is 83800-52S10
157540-8052

Thanks in advance.

OK - 83800-52S10 is listed as being "Puerto Rico Spec". That must mean that for whatever reason the CC indicators are not active. Since your ECM fully supports CC, it sends the messages over CAN bus to the cluster, but your cluster just ignores them. You could pick up a US spec cluster off Ebay and then you'd have the working indicator.

[magnum23]

Ok, I think I will leave it without the CC indicator because changing the cluster implies problems with the warranty, unless I program the current mileage on the new cluster, I dont know why the ECM support CC and something as simple as the cluster, and having the light indicator don't. If somebody find a way to activate that option I will be glad to try it.

CtScott I'm real thankful to you for all your help, and everybody in this excellent Forum.
I will be around trying some different projects and mods from here.

[magnum23]

I dont now it thats just it, but I opened up the cluster and it doesnt have any Led soldered in the cruise and set indicators and also in the Abs indicator, If I solder an Led on the board, should it Do the work? If yes where I can pick up a small led or light to test it?

Thanks in advance.

Update:
I found a post where a member mod the led of the cluster, I will be ordering the leds from ther to see if its works.

That's actually my cruise control indicator module:

I have another question? I did the wiring (blue wire) directly from the computer to the stalk, even when the stock wire goes from the stalk, somewhere else, does that have something to do with the CC signal don't reaching the cluster? I'm just assuming that maybe is an extra wire in the cluster to get the signal that mine doesn't have.

The CC signal is sent via CAN bus message, so there's nothing wiring related to activate it. We've seen this kind of thing quite a bit, where clusters have a capability, but in a particular area of the world it's not active. Unfortunately, there's no practical way to activate the non-active features.

[magnum23]

That's good to know, Scott as soon as you have the ECM repair terminals Im interested in one.
Thanks in advance.

Sorry to be spamming up this thread, but has anybody done a DIY guide for the OEM stalk on a 07-08 Yaris?
