I have take out the door handle to replace the key cylinder bulb because it doesnt work for the first time who I bought the car.
I try to find the wires from the handle switch to check if it is ok but i can not find them
There is no switch on the handle or wires only the two white wires from the cylinder light.
Can some one post a pic were this switch located on handle?
The new handle from mazda comes with switch?If I decide to buy new?
Please check the pic for what switch I talking about.

Ps my car is eu spec with no theft system

the pic you posted is of your CPU. It is in your driver side foot well down on the left side. Those white wires go from your door handle down to the CPU, There is no "switch" that you speak of. If your door handle bulb is burnt out, you can replace it with new bulb. If the bulb is not burnt out and it just wont light up, then its your CPU that is no longer working.

Ok I know that but how the cpu knows that you have lift the handle and then lights the key cylinder?

mazdabation is correct in saying the diagram you provided is of the CPU 1 and 2.

I got your solution though. The switch that basically lights up the keyhole on the door handle and the keyhole on the steering column is on the door handle keyhole cylinder. It is a metal piece that rotates to create a negative pulse that triggers the security system and all the other crap the cpu2 controls.

If your keyhole light doesn't work in both places (exterior door handle and ignition keyhole) then your cpu2 is out. Replace it by getting a used one on the forum or get a new one from Ray for about $160.

Mine was shot and I realized that I had unplugged it for a reason. When I plugged it back in everything was working except I had alot of electrical gremlins. So I'm replacing that as well as my power door lock relay. I think that when the previous owner(s) put in an aftermarket alarm, someone did something wrong and fried a bunch of stuff in the cpu2. Or its the relays/switches all around the car. If that turns out to be my problem then I'll just remove or replace them.

I dont search the reason why the key light did not illuminate ok maybe cpu no2 have problem but i wonder how mazda design this system without any wire from handle switch to cpu no2 .
My guestion is how it is work, ok when you lift the handle then as you said a metal piece give a negative pulse to cpu no2 and illuminate the key door cylinder and the cylinder on steering column, but how that pulse connecting to cpu no2 with out wire.

there should be a wire wrapped in green plastic that runs from the cpu2 harness out through the door panel and up into the door handle
