I wonder how to put in the ECUbox so the solenoid will send the oil properly.

I read this. Someone who can explain a little better.

"The P28 ECU plugs right in, you all you'll Need to do is wire up the VTEC. First, you'll Need to get an engine plug from a junkyard for the VTEC solenoid oil pressure. You'll Need to Run the blue wire (or whichever color is from the plug) to pin D6, and Then run the black ground wire from the plug to anywhere on the engine. hadeeth You Need to run the green wire from the VTEC solenoid to pin A4.
