there isn't one on jdm itr's. they don't use a vtec pressure switch.
usdms do use them though. and any b-series switch will work.

Just splice the VTM wire into the VTS wire and the ECU won't throw a CEL even without a pressure switch.

Sorry i don't understand your short form.
Splice the pressure switch wire into ...what?

VTEC pressure switch into the VTEC solenoid wire. The ECU checks the VTEC oil pressure after VTEC engages, this mod tricks the ECU into thinking there is pressure on the VTEC oil pressure switch. FWIW, this works on OBDI ECUs, I don't know about OBDIIs, but I would imagine they would be similar.
