04 GT check engine light

[mustanglover408]

Im trying to put in an autometer gauge cluster in my 04 GT. Well Ive found every wire tie in except the check engine light. I know that several sources for faults feed the PCM, but where does the signal to illuminate the check engine light on the instrument cluster come from. Any help would be appricated because my head hurts from beating it against the wall

I don't remember I would have to pull mine out to look at it. Don't think I took pictures during the removal and installation of the autometer, but I will look for pictures on my other PC...
