Still, good info tho. Can you access this by jumping two terminals?

Yes, Towny. There is a self-test harness which is attached to the driver's side fenderwell. I made a jumper wire to jump out the two terminals, one from the self-test harness and another from a smaller connector. Then I do the KOEO test and count the "blinks" of the CEL. I could use a scantool but I don't have one.
I guess I could take a pic of it. Yeah, maybe I'll do that. That way people could check their own codes for free instead of going to Vato Zone, since most people who work there I wouldn't let near my car with a sponge, let alone a scantool.
