Hi all the bros and gurus,

I need your advice.

Recently, i just bought an multi-information display panel (with touch screen support) to integrate into my RX330 which is a non touch screen NAV display panel.

The 2nd hand multi-information display panel is from a 2004 RX330 and i have no idea what are the socket behind the display panel meant for.

I would advice the bros here to tell me what is the 4 socket connectors as indicated in the red circle in the image should be connected to?
If possible, it would be helpful if i can get the wiring diagram of those connectors' pins.

Thanks in advance for the advises.
