I have just finished installing my AVIC Z110-BT with rear camera and PAC SWI-PS steering wheel control interface. It took a couple of days, but I finally finished it. The bypass works like a charm as well. Due to the fact that I am overseas (military) I am not using the GPS to its fullest yet, but I still want to connect the vss for future use. I am unable to find the vss on my Ford Edge. Is it on the harness or under the hood? If it is on the harness, what pin number is it? I hope it isn't under the hood

While doing further research, I found a post that has the VSS location

VSS:

VSS = Vehicle Speed Sensor. You don’t NEED to connect this. But if you do, the Navigation is supposed to be more accurate.

 

In the Edge, you can find this wire coming from the PCM (Powertrain Control Module), which is under the hood on the passenger side of the engine. It is the purple/orange wire.
