Hashim bhai !!!
I have compared both pictures of Connector A of clock spring (inside the steering wheel). Before & after installing buttons.
Pin 3 & 4 are connected to multimedia buttons.
Red, blue, grey & green wires are coming out of cruise buttons.
If we see the pictures, those are 5 & 6... not 3 and 4... (1 & 2 are empty) starting from right bottom.
I don't know about the secondary connector that is on the other side of the steering wheel.
Can you be more specific ?
Thanks
