Never tought to check this before. I know it's dumb
I have a 88 gt and i had to remove the instrument cluster to change a blowed bulb. I notice there was no bulb in the Check oil and Check engine. Check oil is not very usefull because on the 88 there's another place to check it but i'm surprised that the check engine wasn't there.
The board connector was so clean that it look like it was missed from the plant.

Anyone have already saw this?
I've installed one then no code. haaaaa i'm breathing
