I had a question in all the videos and pictures i've seen for the brake bypass every one has a white AV harness, mine is black and does not have any extra room to be able to move a 'mute' wire over which it does not have only 1 yellow wire which is the power source. My question is, is this a different version of the Avic Z120BT it says it was manufactured Nov 2010 on the sticker on it. This is a black av harness that has a little tab to hold the fuse above it in place as shown circled in the picture below. is there supposed to be something connected to the AV in/out. i have not got to use it
