Well I went to pull some codes on my GTUs -> Turbo II swap to make sure everything was doing ok and noticed the check engine light was not illuminating at all when you first turn the key. I checked the bulb, swapped it 3 times then swapped in a different idiot cluster and swapped the bulbs in there too. Still no luck, checked some fuses, am I missing anything here? Lemme know guys...
