hello everyone!

I'm trying to install a backup camera with my avic d3 but I can't locate the reverse wire. Does anybody knew where this wire runs. Hope somebody could help me, Thanks so much in advance...

I guess I just have to answer my own question. I found the reverse on the passenger side kick panel. It's the green/black wire. There are 3 kinds green/black wire 2 are small and 1 thicker wire. You just have to use a multimeter to identify the reverse wire between the 2 smaller green/black wire. Back camera now works perfectly.
