  1. Mark, the 2003 Ford F350 speed sense wire is the gray/black wire located in the harness on the interior driver side of the firewall. If your 2003 Ford F350 is a diesel, the speed sense wire is the white/orange wire on the back of the fuse box and is taped to the side of the main harness. The Ford F350 reverse wire is the black/pink wire located in the harness on the driver side frame rail by the door sill. Hope this helps. Good luck with your 2003 Ford F350 navigation installation.

  2. I’m installing a Panasonic AVIC-Z140BH navigation/stereo in a 2003 Ford F350. I need to find the wiring location and color for the Car Speed Signal and the Reverse Gear Signal. Can anybody help? Thanks!
