I cant seem to read my check engine light.

I see a 2pin plug under the dash and i see the test clip by the fusebox under the hood.

I tryed to read it with a multimeter and a 12v test light by connecting to the positive battery lead and the ground clip.

Does any1 know how to read the check engine on a 93 ranger 4.0

You need a analog voltmeter(needle) and a wiring diagram. Maybe better to go to a parts store and have them read it for free. Most places will do that.

do you have the code definitions?

Yes. What codes did you get ?

have you tried autozone to get the codes read? They might have the correct plug to read it.
