Can I connect an "check engine" light to my cars in the dashboard?

the injectionsystems on both cars is KE-Jetronic with Lambda regulation
I have checked some wiring diagrams for non-europeic cars (Fed and Can), and what I can see is wirings for "check engine" from the main unit and the OVP (not standard on my cars) can i do this?
