Help with 2003 Yaris Steering Wheel control adaptor / stalk - Toyota Yaris Forums

I know the thread is very old, but for anyone facing the same problem, which is adapting a Connect2 steering wheel controls interface on a Yaris 2003>2006 (facelift), here is the solution:

The Connect 2 interface has a 20 pin connector with three wires for the steering wheel controls: pink (sw1), blu (sw2), black (swg). The car connector on the original cd player has a different connector with only two wires: yellow and green/yellow. Disregard this connector.

Open the dash just above the cd player, behind the display there is a 8 pin connector with three wires attached: black, red, green. Black here is not ground as you may think! These are the correct connections to the interface: black > pink, red > blu, green > black.
Of course you have to cut the connectors and make the connections yourself. I used some faston connectors.

It took me some time to figure out this, so I thought it would be nice to share it (maybe there is stil anyone in the world with an old Yaris trying to replace the original stereo)
