Check engine light wire
I’m doing a LS swap into my 1972 cutlass does anyone have the diagrams for the bulk head or any idea what color the check engine light is.

There is no "check engine light" on a 72. There are separate, oil pressure, temp, and gen lights.

You will need to put a single light on your dash somewhere and connect it to the MIL wire in the LS harness.
