ok, i dunno about the exact wiring but you will need some vtec solenoid harnesses to wire up the 3-stage vtec solenoid

P28 doesn't support 3-stage VTEC. Just have VTEC-E(first solenoid) always on or RPM-activated switch, and wire the "normal" VTEC and other wires as if you were doing a Z6 swap(OBD0-OBD1 conversion too of course).
