ok after doing some reseach I think I understand. All i need to do is run the vtec solenoid, vtec pressure swtich to A4 & D6 of my obd1 ecu. ground the vtec pressure switch to any ground. And last run the Knock sensor to my ecu which is D3.

IF anyone has done this before please let me know is this all i need to do when I drop my b16a sir II into my 92 LS(obd1) integra.
