Connections:

All connections are at the ECM, which is located in the passenger side footwell, under the carpeting, and under a metal panel.

Here are the pins I used (and also note the wire colors; depending on the vehicle options (with or without ABS, AT/MT, etc.) you may see a different color wire for VSS, but I think the location should be the same.
