hi

I was doing some strange experience yesterday!
I noticed that all my buttons in my instrument panel did noot light up.
So I started to serch for the reason why! I fond that there was no power to the bulbs inside the buttons. Ok so I was thinking that must be because I did remove some off the original ECU harnes last summer.
But I would like to know where and witch wire that conect to the gray wires that go to the buttons?
This wire have to come from interior regulator and I think this wire is green/white or only green. If I am correct where is this conected with the gray wire?
I am not sure but maybe the gray wires get power from the fuse box...

Anybody understand and know this?
