Check engine light question/idea.
 

Ok, so here is my question/thought.

I have a 1989 240sx SE (HUD) And as you guys know the SOHC S13's don't have a CEL do to the fact they are built into the factory ecu. But i have a OBDI 2JZGTE (Aristo) and those usually have a CEL. So i was wondering, Could i find what pin on the ecu would trigger a check engine light to make one of the other lights in the gauge cluster to flash like the CEL would (something like the old battery dummy light, or brake,etc)

thanks - Nick

BUMP.

anyone have some insight?
