also id like to test the VSS output wire. mine is a black wire but its the only wire on either connectors at pin 50. my truck does have a custom harness on it but I would think the PCM still needs the wires in the factory position.

anyway since I cant find an answer via google...what should the VSS output wire read with the key on? should it read differently with the engine actually running? I understand it will send a pulse signal *while driving* but im not sure if there should be any voltage on this wire otherwise.
