My truck VSS sensor has two wires and the 2004 GTP pin-out suggests only one signal wire. Any suggestions on how to wire this?
Thanks.

I think you're looking at the output pin, not the input pins

I'm looking at the PCM connections, it only calls for one VSS connection.

The other pin on the VSS is most likely a signal ground...check the schematic.

I am wiring one now. The ISS is the VSS. The one labeled VSS is only output to the instruments. The actual pins are on the green connector C2:
20 TN1231AT ISS Low Signal
21 BU/WH1230AT ISS High Signal

Thanks for the info. How is your swap coming along? Mine is waiting on the PCM...the car is in Charleston.

Its pins 20 and 21 on the green connector

Do you happen to have a yellow 944? Mine is coming painfully slow. I have the suspension put together but waiting on the motor to go in the car. Just waiting on parts and it is killing me. I thought I would be done by now. So, to pass the time I am starting the wire harness.
