“Wiring harness question... In the manual it says "yellow wire is to be connected to constant 12V supply terminal"... The wiring harness I received with the receiver did not include a yellow wire. Is this normal? I'm thinking that because it was an open box item, that either the wiring harness was messed with and the wire came loose, or that Best Buy replaced the wiring harness with a similar but not exact harness that is supposed to be with it. I will probably be contacting the store I purchased the radio from but I thought I would just throw this up there incase others had any other input or are dealing with the same issue.”
