Not sure what you are asking.
I can help if I know what you are looking for?
What is in your truck now? Aftermarket head unit used with factory components? (Amp and speakers?)
And what are you trying to do?
If you are wondering how to hook up a new deck and are looking for the diagram of your aftermarket adapter then you will need to go to the web site for that adapter and download the manual. Or you can try figuring out the wires from where they are hooked to your aftermarket deck.
My truck is an '03 z71 with bose system in it and I have the factory stuff on DVD so I can pull it up if I know what you are looking for.
