However we will wait for toyota technical , maybe he can help us.
Here in Saudi Arabia no one of the company employees wants to help us !!
They want to get you to buy a car with full options to pay them more money !!
Try the following, (starting from the steps that you did not accomplish yet):
1) Install the aftermarket Cruise Control Switch
2) Wire the negative in the 12-pole connector, pin no.4 (after the steering wheel spring) and ground it to a screw just around there
3) Wire the cruise control signal (pin no.5 of the same connector) and pull the wire until under the glove box, let it arrive just close the ECM.
4) Make sure that the wire at the ECM side ends with a pin exactly similar to that one which You clipped in the steering wheel side connector.
5) Make sure that You will be somehow able to recognize this CC signal wire in future
6) Close the glove box, close the steering wheel shroud.
7) Go to Toyota and pretend that You bought your car with the Cruise Control by OEM and just now it started not working. Swear this is the truth :) and get it fixed by them.
8) Test the Cruise Control in the trip back to home
9) Report if successful, including picture of where they plugged the CC-switch signal wire in the ECM

Good Luck! You can do it!! ???

My friend, this looks a hard thing to get... I mean, destiny against us. but i'm still confident :)
The guy who promised to help me (by forwarding the request to some not better defined "Dubai technical support staff") is now quarantined due to suspected contact with someone...blablabla...
So, meanwhile we wait for him to be back to work, as You are from Dubai (or at least, so it looks like to me...) We might try to work both, in parallel, on two fronts.
Apparently our models (2012-2014 MTM GCC FJs) are equipped with a strange "8966135k90" ECM whose terminals' design does not look like in the other FJ's.
The question (to anybody at the Toyota Technical Staff - Dubai) would be "Dear, pls. could You browse the electric maintenance manual of my 2012-2014 Manual GCC FJ and send me a printscreen of the ECM terminals design & legenda?"
If by doing this You don't get a clear-enough diagram, try to address Him to the pages of the Cruise-control troubleshooting.
If he wants a bribe, we can share the expense. But if the image doesn't match our ECM, we will want our money back :) :) :)

I'll let You know if from my side i can get something...
Awesome - Thanks

I figured that out and which pin to connect it to on the ECU, but I messed the terminal up, so I need a replacement terminal for the ECU connection. There is also a possibility that I need to connect the clutch switch. The Cruise indicator is another ECU connection, but I don't think that will be required to make it work.

The connector is the 2nd to top (E77), and it is position 11 that you need to push the terminal into.

The other end of the ECU wire needs to go into the spiral connector along with an earth into the same connector. Let me know if you need to know where that is.
My Friend i found a guy who uses to fix everything...
1) he checked my case and found the right pin where to plug the wire from the steering wheel spiral connector. This was confirmed by running the diagnostics (he plugged the computer to the car and the stick switch was delivering the ON/OFF , UP, DOWN, CANCEL signals to the ECM. This after a couple of unsuccessful attempts due to bad quality of the pins which came with the aftermarket switch stick (you never know if they are fit properly until you can't test them with tester OR by comparing the computer diagnostics). And let me say, it looks exactly the same pin 11 that you have in that picture (it should be the TACOMA ECM connector design) (or maybe the Prado's)
2) By observing the same ECM connector he found that the pin which should be the clutch pedal switch was wired at the ECM side. He watched the pedal root, and the switch is there. Note that the switch must work properly otherwise the cruise control can't be activated (this is part of a safety protocol, he says)
3) Drive test. Cruise control still not working
CONCLUSION: The clutch switch at the pedal's root must be not working

So if You now say that the switch is there, but no harness connected to it... and You always started the car without need of depressing the clutch (as i do as well), at this point i have another question mark: why shall Toyota sell cars with sensors in place but not wired? doesn't this sounds just crazy...??

Can You confirm to me bcs i'm afraid that i might have not understood properly: You saw the switch, but it's not plugged to any harness, so in other words the switch is there but it is doing just the job of a common, blank screw to adjust the mechanical stop of the pedal and nothing else?

Immediate update:
I knew i couldn't sleep for that tonight, therefore i went down to check this out.
And i came back with same amount of doubts.
There are 2 limit switches in the clutch. One at the beginning of the stroke, one at the end.
A) The one you saw non-harnessed, is at the end of the stroke. If wired, it would prevent the engine from starting unless you depress the clutch until the end.
B) The other one (which i think you did not see) operates at the beginning of the pedal stroke (as you lay a little of pressure with your foot on it) and is the one which makes sense to be needed for the cruise control. And i just saw it's wired, also at the switch side.

So, i will follow the advice of my "Guru" and change the switch B (part no. 88280-14030) and see if it works.

I'll let You know when i will be driving with the feet on the carpet :)

Some great detective work!
I was just thinking of putting a switch in the dash with 2 positions - start and cruise...
There is a valid reason when offroading to start the car in gear - so you don't have to ride the clutch or over rev to get going - Works best in low range.
