Default vtec pressure switch bypass obd2a??

Got a 97 JDM GSR motor and noticed it doesn't have the vtec pressure switch so I was doing some searching but all I can find is bypassing it for OBD1 ECU's. I'm running a USDM P72 so I'm not sure how to bypass it. All I found was to bridge A4 & D6 but that's on an OBD1 ECU.

So for an OBD2a would I jump A8 and D15 then ground the black wire off the connector?

you jump 2 wires together on the harness. i don't remember which ones right now.
if you search for VTP fix on pgmfi.org you will find it. this is why way i did my last one

Awesome, much cleaner fix than jumping more wires on my harness.

Thank you!!
