I have purchased an aftermarket android based stereo, nav, dvd etc system for my 2013 RAV 4 and all plugs are compatible with existing wiring except for a socket coming out of the stereo with 3 pins that is K1 and K2 plus earth. I believe these are to control steering wheel volume. The Toyota wiring harness plug has multiple wires and I need to know the colour scheme of the wires coming from the volume control on the steering wheel so I can adapt the stereo plug to suit.
Has anyone a suggestion to solve this problem as I miss the convenience of steering wheel volume control. The stereo has a feature to "learn" the steering control once I sort out the wiring.
Thanks in anticipation.

It looks nice!! (it says "Do no ship to US", how did you buy it?)

You need a canbus for steering wheel volume control. Following one is I got:

Canbus of car dvd accessories just be sold with car dvd on Aliexpress.com | Alibaba Group

When I bought the head unit I also bought canbus for wheel volume control. It pre-connected to main harness when it came. Different head unit, canbus connection is different. You can contact the seller about that.
