UnitedMotorsport 55 Posted April 26, 2009 Report Share Posted April 26, 2009 Depending on what OBD1 you are running at the moment, you might need to change the lambda probe as they have different connectors. Link to post Share on other sites

UnitedMotorsport 55 Posted April 26, 2009 Report Share Posted April 26, 2009 3-1 is how all the sensors are.Being a 93 version you probably have the square plugged probe.You can hard wire it, but be aware these sensors work on very small voltages, so any interefence makes a big difference.
