does anyone know if the 1998 honda accord ecu plug is a obd2a or obd2b? we purchased a obd2a-obd1 harness adapter and it did not plug in. so i assume that it is a obd2b plug but we wanted to make sure. does any one know?

thanks

 

it is obd2a and im not sure but i believe that obd2a and b have the same plug dont they

 

its obd2b, the a and b have the same plug set, as in the 4 plug design. but use differnt pin asignments.

 

I thought honda switched to obd2b in 2000?
