The OBD-2 engine harness doesn't plug into the OBD-1 Civic chassis harness... it will be EXTREMELY difficult to do what you are trying to do. I suggest you rethink your plan.

This is the proper solution.

SERIOUSLY !?!? You know what you have to do... even though you don't like the answer. Stop "hoping" for something easier and get to work.
