HELP SETTING UP THE STOCK BOSE RADIO ON A 2003 ALTIMA

[argpav290]

I recently bought a 2003 Altima with the Bose system. It came with an aftermarket eq but I didn't want it so I told my friend to help me get rid of it. Well it turns out he cut the wrong wires and now nothing works. All I want if for the stock system to work. I have been trying to look for the stock harness but I haven't been able to find it. Any help is appreciated on where to get the wires, how to install them. Pictures.Again just want the original stock bose system running n I just need to fix the wiring.
