I’ve got a 06’ Explorer. I’m 99% sure it’s prewired for the factory NAV unit witch is made by Pioneer witch has to have the VSS wire hooked up. So I want to install an aftermarket unit made by Pioneer. So I figure the VSS wire has to already be there behind the factory stereo, but witch one is it?
I had a Kenwood unit installed but someone wanted it more than me I guess. But it didn’t require the hook up of the VSS wire. However when I installed it I did notice there were a couple extra wires in the factory head unit connector. I figure one of these has to be the VSS wire for and if the factory NAV unit was installed.
But witch one?
