Have you narrowed down what the electronic box does?

Then use the TIS to locate the the box and then its wiring diagram and connector number.

Is this the part?

Just like posted above, since your RX is non-nav, look for the Audio system.

 

Salim, that's the part in working on, I need the wiring diagram for the connector that goes from the car to that part. I can't find the diagram in the TIS site or any working diagram that is relating to Non nav set up. Maybe I'm not filling understanding everything I'm looking at either. I think my only option is to pull apart another RX just like mine, unless someon in here is nice enough to take a picture of theirs and share.

Thanks for everyone's help, it's greatly appreciated!!

 

Have you been able to download the wiring diagram of the audio system? That joystick/remote should be in it.

 

Ask the suppliers if they have a diagram, ebay or online. You can chat with the parts supplier viad_a linked.

 

Looks like I have stumped a Lexus tech, they are not sure where the brown and white wire go being their digagram does not show those wires......strange
