08 F-150 VSS wire location — AVIC411 Forum Archive

I was wondering if anyone has installed a z2 or z3 in their 08 F-150 super crew and knew where the VSS wire is located at. I have heard conflicting reports about it being at the radio harness. Also if anyone has any tips on installing it that would be appreciated. Thnx

Yes there is a strong possibility that it will be in the wire harness... I dont remember which one it is though... easy way to test is to take a multimeter and set it to AC volts and have someone srive while you test the wires. The voltage should fluctuate from 0 to about 7 volts and it will change with the speed of the vehicle. Some Fords don't have that wire though, only the ones that came with factorty Nav as an option.

sorry I couldn't be more helpful.
