96-98 is OBD-2A, 99-01 is OBD-2B. You'll have to modify your stock engine harness to work with it as the EK harnesses run all the way to the ECU where the DC harnesses plug into the chassis harness while still in the engine bay. If the ECU you get is OBD-2A, there are several companies that make appropriate conversion harnesses.
