Actually I think your right. b18a is cable and OBD0 or 1, b18b is hydro and OBD1 or 2(a/b)im quite sure that b18b1s spanned both obd2 and obd1. i could be wrong, but one of my exs had a 95 teg and she had a b18b1.
Not all right info.
B18a was from 90-95. It was cable in 90-93 and hydro in 94-95. 90-91 is OBD0 and 92-95 is OBD1.
B18b was from 96-01. It was always hydro. Its OBD2a and OBD2b but I forget the year it switched.
Read the whole thread. I was already corrected and said that I was wrong.that is also not true...my dad bought a brand new 94 teggy in 94 and it had a b18b1
