I just installed D3 in 2007 Ford F250. If they have the same wiring. the speed sensor wire is the grey with black stripe wire in your factory radio harness. the reverse wire you can find coming off the steering column. behind the lower dash panel (where fuse box is) the wire is light blue with a black stripe. going into an 8 pin block. Like I said that is how it was on my F250. Hope it helps
