I was asking about the speed signal wire the other day, well i found it( It's on the wire harness that is connected to the dash instrument panel(dark geen with white stripe) I put the pioneer avic-n1 system in and it's awesome. The reason I needed that was There's a screen that tells your speed and the volts your pulling your gforce and angle and also the gps movement. So if any one gets a system like that or similar you'll have a idea were to find that signal wire.
