I'm trying to find the location of the speed sensor wire in my 2000 venture minivan so I can hook up an aftermarket navigation system. Any suggestions? Thanks!

 

go to the cruise module under the hood. If you don't have cruise, the connector is usually tied up under the hood near the air filter box somewhere.
Pin K is a dark green wire, that is your VSS
You can also get the wire at the PCM, Connector 1 pin 55 Dark Green Also

 

Thanks for taking the time to help me out. I found it and can finish my installation!!
