The one wire for the solenoid goes to the ECU. The two wires for the pressure switch only need to be wired if the ECU looks for the switch.

using a switch will work.... but may damage your rockers and valves if switched on too early....the d15b that doesn't use the pressure switch depends on the engine to be at a high rev(above 3000prm) to have enough oil pressure to safely activate and operate vtec.... better to use a rpm switch or use a 12v shift light and set it to 3500-4200rpm...but you will still be running non-vtec maps so you won't get the real benefit of having vtec..
