so I have a H23A in my ek hatch and its time for me to wire up vtec. im using a 96-98 DX wire harness and a obd2a p72 ecu.. I pined a wire into the harness plug where the vtec pressure switch goes and connect it to the solenoid. soo after that what else do i have to do? I know i need to ground it but from what wire since its only one green/white wire on the plug itself.

 

The h23a doesnt have a vtec pressure switch so just ground the wire you pinned from the ecu..now pin a wire from vtec on the ecu and run it to the solenoid
