Those two wires will not be used. With the original radio, the orange / black tells the display to dim when the headlights are turned on. The light blue / red comes from the dash light dimmer and tells the display how much to dim. Ford has always done everything very differently from all other manufacturers. This dimming system is a perfect example. I'm right in the middle of building a new radio workbench, and for the first time I'm going to be able to test remote amplifiers and display dimming operation. I have to build two totally different display circuits, one for Fords and one for everything else.
