Yeah I already have an after market installed. For the VSS, I haven't personally opened up the dash and looked at it, but apparently (at least for the newer F-150's) it's located in the stock wiring harness. It didn't have a stock Nav system installed, but it does have that option were the stereo volume increases as you speed up/down. So I'm assuming that is why the VSS wire would be in that location.

Cool..thanks for the reply. From what I've read on the VSS wire, it's the Gray/Black pin 14 on the radio harness, in case others need to find it

Hello all, My wife will be purchasing the 90bt next week as a b-day gift for me I now have installed in my 04 f-150 the avh-p5700dvd. My question is, do I need to buy a new wiring harness for the 90bt or with the one already installed work? Thanks
