There should be a VSS wire inside, The junction block driver side floor( where all the accessories plug in).  On the back side there will be two brown plugs (I'll have to double check my notes at work tomorrow). The lower plug will have a GREEN / WHITE wire in it. Thats the VSS wire.

I just checked my notes. The 07 has four plugs on the back of the junction block. There are two large plugs, one gray and one black. The VSS is in the black plug. My notes say Green /White bottom row.

I have a picture in my notes which shows the correct wire tapped, but I cannot upload a 62Kb picture. I can only assure you its there.

i did find a yellow/black wire at the ecm in the 07 I did the other day. I tested it with my DMM and it seemed like it worked (changed w/ speed). However, when I hooked it up to the D3, instead of showing between 1 and say 10 for speed pulse, it was going from 1 all the way up to around 200... but it was 100% linked w/ speed (tried just revving to check it possibly tach). It just seemed like it was producing more pulses than a normal vss. Either way, the screen wouldnt read it, so I disconnected the wire, and explained my findings to the customer. He didnt seem to mind, so I sent him on his way. What else could that wire have been besides speed pulse???

Ranger is right. I do them all the time, go to the junction block under the dash next to the brake pedal. Unclip it and spin it around. The big plug in the center, GREEN / WHITE. Very easy to get there....
