I am installinf AVIC_D2 and need to know where the VSS Wire Location is as wellas where the best place to get a Reverse Signal is.

 

I think the wire you are looking for is the same thing I used to hook my superlift truspeed up to... What year is your truck? mine is a 2001. I think it was a grey/black wire.... It was located up near the driver side fender under the battery tray... I am sure someone will pitch in... You could also look up the superlift web site...maybe there are some install directions..
good luck,
Steven

 

Its a 2005 F350 Super Duty Crew Cab

 

05 has vss signal on the factory radio harness gray with black

 

The VSS is gray w/black on the harness going to the factory radio. As for the reverse wire, I just tapped the back up light wire (in the main bundle running along the frame) as it was the easiest to find. Maybe someone else knows an easier solution.
