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

the blue wire have +12v when i release the clutch in link with the white wire?

because i don't have any power on my clutch switch.

my wire are clutch switch +/- to fusebox (white and blue wires )

Correct - When the clutch is not pressed the blue gets 12V from the white and when it is pressed it opens and the blue has 0V.

and this cruise control have a fuse anywhere, in case of shortcut ??
what's happen if utilise N.C switch for testing purpose?
in exemple the first switch are N.C (pin 40 to this switch) , and for the second switch i utilize an N.O switch?
the n.c switch when i push on it its "ON" when i repress on it its "off".
and the second switch its "set"

No fuse - This is just an analog input to the ECM.

A NC switch won't work. The ECM expects to see the input float and then get pulled down to a specific voltage range for it to register. I have reverse engineered the Toyota diagnostics CAN Bus comm to read the cruise control switch state from the ECM, so I can watch how the ECM responds to the inputs.

Have you measured your resistors to see exactly what they read resistance wise. Sometimes you can get a batch that are really at the end of their tolerance band.

i don't know what is the way to test resistors...
12v on a side of the resistor and read the other side?

Resistance setting on the multimeter. Measure with no voltage applied.
