I am trying to find out if anyone has a diagram of the head unit wiring harness for a 2002 Nissan Altima.

Thanks in advance

The L31 altima uses the same head unit wiring harness as all Nissan's 1995 and newer do. When I fiddled with the head unit on my 2005 last year, I used this diagram from installdr.com and it was correct.

Hope this helps!
