Hello all. I'm hoping for a little help here. I have a 1995 Olds Silhouette. This is the year they were transitioning OBD ports from OBD1 to OBD2. I am aware of the paper clip trick on OBD1 ports to read trouble codes by shorting the "A" and "B" terminals, but mine is different. I have no lead going to the "B" terminal. My OBD plug only has three wires going to it, and one of them is not to the "B" terminal. I have been to every auto parts store and two mechanics now...nobody can figure out how to read the trouble codes with this specific plug. Anybody have a similar experience? Is there any way for me to pull the codes without paying a dealership $100 to do it?

Thank you all in advance.

Cliff
