I am planning on installing a Nav unit in my 08 f-150 super crew and was wondering if anyone knew where the VSS wire is located so i can tap into that. I have done some research and found conflicting reports about it being at the radio harness. I found that it might be the grey/black stripe wire at the radio. So any info or tips are appreciated. Thnx
