Trying to wire in dash light for the ford performance wiring harness on my Gen3 Coyote.....

The wiring harness comes with an LED setup right next to the OBDII port. I figured that it would be triggered by a 12v wire, but when I tried to tap into it, I noticed that I have 12v to that light is on 100% of the time (even with the motor off) - yet.... the light isn't on? Is this somehow triggered by the ECU tying the light to ground instead of tying it to 12v?

FYI - I'm not just trying to put an LED on the dash. My gauge setup has a CEL icon built into it, and that is triggered by receiving 12v.....
