I have the factory radio with the extra 20 pin connector. It supports speed sensitive volume control, but it is not wired in on my vehicle. I believe that the needed signal comes in on pin 9 of the 20 pin connector, but I am not sure which signal to connect. Does anyone have a wiring diagram that calls out the Ford signal name for pin 9? Or does anyone have the pin connected and could tell me the colors of the wire?

Thanks,
Joe

 

I sent a reply post about an hour ago and it never showed up ......I will make this one shorter ......try turning on the radio and holding the volume **** in about 3-4 seconds and this should do it I think. adjust sensitivity by turning volume **** after it shows speed sense or something like that......mine has it and I dont see any sensors anywhere so not sure where the pickup is
