Guys, I have searched for a few days now and I guess I'm confused on what to do with the Metra harness. I got a avic D3 from a buddy who had it in his 350z, he gave me the harness that he had for the Z with the unit. I want to keep my Bose setup, so I ended up getting the Metra 70-7551 as well. After taking the factory stereo out and mounting the D3 to the bracket, I am left with 2 extra plugs, CD Changer plugs I'm assuming and the harness that he gave me plugged right up with the factory jacks. Now the Metra harness has the RCAs that other harness does not have, how exactly do I connect the RCAs to the stock amp?? can somebody please clear this up for me.
