Lextek Posted September 23, 2012 Report Share Posted September 23, 2012 Hi jhoy, Newb here as someone gave me a d3. The wire you want is Pink. In the D connector on the back of your instrument cluster. Pin 4. Let me know if you cant find it. I think its the only pink wire on the cluster. That wire should provide VSS as required by the d3.
