Thermocouple
This connector is a standard miniture K-Type, if a sensor is wired correctly and plugged in it will work. NB: The linearisation for any sensor configured to use this input should be flatline 0 this will cause the built in curve to be used. It is possible to specify custom curves but this is only appropriate to the most advanced engine developers.
General Notes
These connectors have a standard pinout. Any future products will feature the same pinout, so a lead made for an NTK sensor for a Subaru MY92-96 will work fine on an Evo VIII (when that carrier board is released). Any external interfaces created to these pinouts should be inherently safe if moved from one model to another; moving an external device which used IGN3 on an MY99 board to an MY92 board will cause that function to simply turn off, rather than be in an uncertain state.
