My 06 gs300 radio wasn't working (came like that). I decided to install an aftermarket, When i removed the old radio, the harness wires was cut. It looked like the dude bypassed the factory amp, new wires ran throughout the car. I guess when he traded it in he took it all out and put factories back in. I cut up all the wire to look for ground,acc and constant, couldn't find any of them. Thanks to a member here, he told me which pin did what. I was able to get the radio working, but the display is working. I press climate button and it say "Please check air conditioner connection" error, none of the a/c controls work. i was told to jump pins 4 to 13, press breaks 8 times, yea that didn't work.. Anyone out the has wire diagram?

 

No one with a diagram or can point me to where i can get one?
