Has anybody got a wiring harness pinout diagram for the 55900 heater control unit(T25 Avensis-2005 ) . I looked everywhere,but can't seem to find anything.

Thank you

The electric diagram is too large, can't zoom in, useless.

Try to upload .pdf file tomorrow.

Thanks for the quick response. My unit is slightly different, it has one 24 pin connector and one 20 pin.

thank you. I spent some time on this, but cant figure something . is there a way to tell which pin or pins(from a15 or a16) is responsible for the illumination of the  buttons?

The illumination wire is in plug A16, pin 23, green wire. It should work only then the lights are turned on from the light switch.
