bluegp Posted January 23, 2004 Report Share Posted January 23, 2004 For the '96 Lumina: Does the speedometer use the same pulsed signal as the other GM cars and is the tach signal the same also? None of it comes from the Class 2 serial data bus, correct? In other words, would a speedo & tach from another car work? Quote Link to comment Share on other sites More sharing options...
Dirty Rockstar Posted January 23, 2004 Report Share Posted January 23, 2004 It should.. most GM speedos use 4000 pulse per second speed signal/sensor.. I know my Pontiac 6000 has this, as do Bonnevilles, and Grand AMs. Quote Link to comment Share on other sites More sharing options...
