I have a 96 del sol s, with a 2000 b18c1 in it. How can I tell if I am obdIIa or obdIIb? The guy who did the wiring for me, is no longer availble. Is there any information you guys can offer to help me out. I am planning on going to obdI and need to know what kind of jumper i need. Is there a way by looking at the plugs to see if I am A or B?

 

Here's a pic of all the ECUs. Top is OBD2b, next down is OBD2a. I just posted some stuff in the hybrid forum asking about the same thing more or less.

EDIT - 96 should have an A wiring harness but the motor would have been a B if it came with the original ECU. Best thing to do is pull the ECU and compare. I'm betting OBD2a.
