I've been lurking around here for a month or two... I'm finally getting ready to install my D3... everything seems pretty simple and searching has answered all but a couple of my questions...if some one could answer them I'd really apreciate it.
It will be installed in an 07 F150 Lariat without sub...
1.) The pac Harness I recieved from Crutchfield has a wire for the dimmer. But in some of my searches I have heard people are not using it on some Fords...will the Pac harness wire work correctly for the dimmer? or do I need to tap the parking lights?
2.)for the VSS I understand that you can use the use a wire behind the factory stere if it has the speed sensitive volume (mine does) I have read that it is a black/white wire??? can someone confirm this or shed some light on it?
3.) im not installing a back up camera do I need the violet/white reverse signal wire?
If anyone can answer or help me with these questions I really apreciate it...I'd search more but my computer time is very limited...thanks guys!
