I've had my head unit in since Christmas and finally decided to run all the wires for the gps unit and get it working. Got it all hooked up but the speed sensor wire dose not register with the unit, i looked up and found the wiring diagram and it said it was a dark green/ yellow wire. I had the stock gps unit in the truck before so i saw a dark green/ yellow wire behind the head unit so i taped into it. But it won't read it, so i was gonna hook it up to the pcm tomorrow when i get time and see if that fixes it. But after looking up on here though i saw a post that said the speed sensor wire is blue and located on the bottom black plug of the pcm, The wiring diagram i found said it is dark green / yellow and on the white pcm plug. So which one is it actually?
