Wire harness

[DeCoY]

I am putting an OBD2 b18c GSR into my 1990 honda civic SI. My mechanic told me my car is OBD 1, but i am still skeptical. What OBD is my car? And what harness will i need for this motor? THANK YOU VERY MUCH


My car was built on July of 1990

your mechanic is a retard all 89-91 civics were OBD0 stock. Is it possible that your car was already converted to OBD1?
