  1. Hello, does anyone have a wiring diagram for the 2004 Lincoln Navigator Overhead DVD player wire harness? It’s a 12-pin connector. Thanks in advance.

  2. I have a 2003 lincoln navigator and I’m installing a pioneer avic z140bh. I have the harness but I can’t find where to plug the harness for the factory amp? anyone know?

  3. Joshua, thanks for the 2003 Lincoln Navigator factory amplifier power wire information contribution!

  4. Thank you ModifiedLife for you help. I already found that the amp power cable is a green with a black stripe. It may be is different because my truck is the late production or something like that. Because when I took my truck to a car audio dealer, this guy said nothing can be down but I tested all the cables and found the correct. I hope this can help to others, I gonna try to upload some pics.

  5. I have an 2003 lincoln navigator with the OEM Navigation. Some of the later 03s and the 04s have a the navigation with the larger screen. I was wondering if there is a way to find out if the newer larger screen system is able to replace my older small screen system and if it would just be plug and play or will it require massive wiring changes. anyone?

  6. Joshua, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 2003 Lincoln Navigator may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier to output sound from your speakers. Hope this points you in the right direction. Good luck with your 2003 Lincoln Navigator stereo installation.
