Hey gentlemen, I recently had my truck broke into and the nice fella that needed my stereo must have needed the factory plug too. I have a 2005 silverado with steering wheel controls and have no idea what the wires are. I have a small orange wire, a larger orange wire and a black with white stripe wire. The speaker wires of course but they are all twisted together so they are pretty self explanatory. I would have thought with steering wheel controls there would be more wires. Can someone tell me the pinouts so i can connect to aftermarket radio? I appreciate the help.

 

if you shoot pm me with an email address i can get you a pinout
