Looking at the diagnostic unit on my 88 pickup I cannot find TE1 anywhere. On the diagram on the inside of the unit's cover there is a T but no TE1. I do, however, have an E1. I'm curious if T is actually the same thing as TE1, but when I jump it and E1 I don't get anything... This truck is such a beater I'd be surprised if the ECU didn't have some codes stored somewhere...or else even that part of the truck doesn't work either...

At any rate, I'm just curious how I'm supposed to pull codes off this thing (if it turns out that I even can).
