SCOOBY STEVE

So, I'm selling my motor swap, everything included. I have a guy I work with who has a 92-95 Civic hatch who is interested in buying the motor. He made mention that supposedly they are already wired for VTEC because of the VX/SI. He said he wasn't too sure. The reason I am asking is becasue I told him I would help him. If this is not true, someone show me where to find diagrams on extending a p73 harness, or adding to the stock harness.
