2007 Ford F350 Avic D3. Could you be real specific on the reverse wire location. I have a couple of wires that look to be black/pink in the back of fuse block. If possible could you give me the relay or fuse position from the front cover of fuse block. (example: relay 14 or fuse 12) Thanks.

use a test light or meter to check. cant anyone find anything on their own. you shouldnt just hook up to a wire because someone on here told you it was the right one. you need to test and confirm before connecting
