A four pin coax will probably be RGB and composite sync.
The comp sync signal has to be converted to horz sync and vert sync.
GM/DELPHI used this on my CTS-V.
I hope FORD is better at releasing information then GM/DELPHI.
I had to reverse engineer the interface I use.
Furthermore, the OEM display would not handle the bandwidth required and I replaced it with one that could.
This will give you an idea of what I went through, but I got it to work!
Thanks, I'll take another look. I picked up a 2nd display cheap on eBay that works fine. I popped it apart and tried to figure it out. I also have a video module that puts a picture on the screen which is where I found the chip. Your RGBs seems more likely but it looked like only one of the 4 pins was being used. But its hard to tell. I'll take another look.

If anyone is interested, I finally found a place that can do custom programming of these radios... www.4DTech.com Not only can they program pretty much any setting you want, they seem very knowledgeable about what the settings do and these radios in general.
