Is the P13 ECU right for a H22A4 engine?

I have a 1993 SI with a 99 H22A4 swap done by the previous owner, the ecu is the P13 correct for this engine and if so how do i wire the vtech back to it. He had the vtech on a button and i dont see any spare wires on the ecu to wire it correctly.

The P13 is a VTEC ECU but it's for a 93-95 OBD-1 H22A or H22A1 4th gen, not a OBD-2 H22A4. Hopefully there is a OBD-2 to OBD-1 conversion harness in there somewhere too. The P13 should have a wire for the VTEC solenoid, they either just wired up a button to be awesome, because NOS, or the car was originally non-VTEC and they could not be bothered running the extra wire or buying the right ECU.
