Alright so heres what I need to know. How to wire vtec if running a p28. I know there is no pressure switch and the chipped ecu will have knock sensor disabled. So basically in my head all there need to be wired is the main vtec wire. Is there a spot on the tower plugs or do I have to wire straight to ECU? Also since its a p28 and there is no purge solenoid on the motor, what do I need to do so it won't throw a code?
