does a 93 dx hatch have OBDII plug
 

Where is the OBD II plug at if there is one? i am wondering how to use the JET V-Force Plus Performance Module i heard you plug it into a OBD 2 port.

If your car still has the stock engine, no, you don't have an OBD-II port. Those started in 1996.

Any pre 96 Civic was not OBD2. /story
