Hello all, im teying to rework a stock harness from a gen 2 coyote to work as a stand alone, im pretty much on the last stages of it but I cannot seem to find what are the pins or wire that turns on the MIL, my understanding is that pcm grounds a light that already has power but i cannot find the pin or wire, again this is for a stock harness. Thank you all in advance.

Pretty sure it needs to be tuned out. Its not as simple as jumping or removing wires.

Michael- you are correct and pcm has been flashed to remove pats/security, i just need to find out what wires the pcm uses to turn on the mil/light. Thank you for your reply, appreciated

A Ford Performance Control Pack tune would be loaded into the PCM. This will repurpose the EVAP solenoid output to a MIL/ check engine output.

Hey sparkymark, thank you for your input on this, so on the tune they have to make changes to repurpose evap solenoid output to mil output. got it. Again thank you for the clarification. Appreciated.
